SAN DIEGO (AP) — As thousands of migrants in a caravan of Central American asylum-seekers converge on the doorstep of the United States, what they won't find are armed American soldiers standing guard.Instead, they will see cranes installing towering panels of metal bars and troops wrapping concertina wire around barriers while military helicopters fly overhead, carrying border patrol agents to and from locations along the U.S.-Mexico border.That's because U.S. military troops are prohibited from carrying out law enforcement duties.RELATED: Migrant caravan groups arrive by hundreds at US borderWhat's more, the bulk of the troops are in Texas — hundreds of miles away from the caravan that started arriving this week in Tijuana on Mexico's border with California after walking and hitching rides for the past month.Still, for many migrants, the barriers and barbed wire were an imposing show of force.Angel Ulloa stood on Tijuana's beach where a wall of metal bars more than 20 feet high cut across the sand and plunged into the Pacific. He watched as crews on the U.S. side placed coils of barbed wire on top.A border patrol agent wearing camouflage and armed with an assault rifle — part of a tactical unit deployed when there is a heightened threat — walked in the sand below where the men worked. A small border patrol boat hovered offshore.RELATED:  CBP commissioner nearly clobbered with rock at while touring Friendship Park border"It's too much security to confront humble people who just want to work," said Ulloa, a 23-year-old electrician from Choloma, Honduras, who joined the caravan to try to make his first trip to the U.S.Now, he and his two friends were rethinking their plans. They tried to apply for a job at a Wal-Mart in Tijuana but were told they need a Mexican work permit. So they were considering seeking asylum in Mexico but were unsure of giving up their dream of earning dollars."We're still checking things out," he said.On Friday, people walking through one of the world's busiest border crossings into Mexico passed by a pair of Marines on a 20-foot lift installing razor wire above a turnstile.RELATED: Photos: Aerials of U.S.-Mexico border fenceNearby Army Sgt. Eric Zeigler stood guard with another soldier. Both were military police officers assigned to protecting the Marines as they work.The 24-year-old soldier from Pittsburgh spent nine months in Afghanistan. "It's very different over there, obviously. It's a lot more dangerous," Zeigler said.He said he was surprised when got his deployment orders sending him to the U.S.-Mexico border."But I'm happy to go where I'm needed" he added as a man walked by carrying shopping bags headed to Tijuana.The U.S. military has deployed 5,800 active-duty troops to the U.S.-Mexico border.RELATED: Video?shows people climbing on top of border fence near Friendship ParkSo far, more are not expected, despite President Donald Trump's initial assessment that 10,000 to 15,000 were needed to secure the border against what he has called an "invasion" of migrants. Most in the caravan of several thousand are families, including hundreds of children.Another 2,100 National Guard troops are have also been deployed since April as part of a separate mission. Like the military troops, they are not allowed to detain illegal crossers. Instead, they have been monitoring cameras and helping to erect barriers.Of the 5,800 soldiers and Marines, more than 2,800 are in Texas, while about 1,500 are in Arizona and another 1,300 are in California. All U.S. military branches, except the Coast Guard, are barred from performing law enforcement duties.That means there will be no visible show of armed troops, said Army Maj. Scott McCullough, adding that the mission is to provide support to Customs and Border Protection."Soldiers putting up wire on the border and barriers at the ports of entry will be the most visible," he said.Marines and soldiers share the same duties in California and Arizona. These include erecting tents, setting up showers and arranging meals for troops working on the border, and assigning military police to protect them.There are no tents or camps being set up to house migrants, McCullough said. Medics are on hand to treat troops and border patrol agents — not migrants — for cuts, bruises and any other problems.Combat engineers — whose duties on the battlefield include setting up tactical obstacles to prevent the enemy from moving freely — are using their expertise to string wire on border walls and erect temporary fencing, McCullough said.Construction engineers have been assigned to weld together barriers and move shipping containers to act as walls.In Laredo, Texas, about 100 soldiers have been installing three layers of razor wire along the Rio Grande, working on the banks during the day and on the bridges at night to minimize the disruption to cross-border traffic.The current mission is scheduled to end Dec. 15 for now. It's unclear how much it will cost and military leaders have refused to provide an estimate.Critics have questioned the wisdom of using the military on the border where there is no discernible security threat. Since the Nov. 6 elections, Trump has said little about the matter and no border threat has materialized.Some border communities fear the barricades will scare off Mexican shoppers. The city council in Nogales, Arizona, slashed a proposed bonus for all employees in half over concerns about how the military's presence would affect its sales tax revenue after the military closed off two lanes at its border crossing.Defense Secretary Jim Mattis defended the deployment during a visit to the Texas border this week, asserting that in some ways it provides good training for war.Suyapa Reyes, 35, said she was puzzled as to why she would be seen as a threat. Reyes, her mother, 12-year-old daughter and 16-year-old son left Honduras with the caravan on Oct. 13, fleeing violence and poverty in her hometown of Olanchito de Oro.She does not want to return after coming such a long way but if she cannot get asylum and the border looks too dangerous to cross, she said she'll have no other choice."I'm not going to risk my life or safety nor that of my children," she said. 6241

SAN DIEGO (CNS) - A construction project at the Edward J. Schwartz Federal Office Building in downtown San Diego will result in a 21-month closure of a portion of Front Street, beginning Saturday.According to the U.S. General Services Administration, a two-block stretch of Front Street, between Broadway and West F Street, will be affected by the construction project, which is expected to last until June 2021. Pedestrian and vehicle traffic will be detoured around the project area.The project will reinforce and enhance the Front Street underpass beneath the Schwartz Federal Building. The project is designed to increase safety for the building's occupants as well as pedestrians and motorists, according to the GSA.The Federal Building's existing framing at the underpass will be reinforced with new steel beams, concrete paneling and column support structures, federal officials said.Signs will be in place on Interstate 5 to alert motorists to the closure as they enter downtown. The easternmost lane of Front Street between Broadway and E Street will provide access to the underground parking garage at 101 West Broadway and for turning city buses.Construction work hours will be from 7 a.m. to 5:30 p.m. except on weekends and holidays.The roadwork will be completed first, followed by pedestrian walkways with full-height walls to separate the road from walkways, according to the GSA."One of our strategic goals is better management of federal real estate and this GSA construction project allows for that while also being a catalyst for downtown revitalization," said GSA Regional Administrator Tom Scott. "By enhancing the Schwartz Federal Office Building's structural integrity, we're also providing a safer public space in partnership with the community." 1779

SAN DIEGO (AP) -- Smoke from the fire that ravaged a Navy warship in San Diego Bay contained elevated levels of toxins, but air-quality authorities say area residents have little to fear.The San Diego Union-Tribune says the local Air Pollution Control District found smoke from the USS Bonhomme Richard contained a dozen potentially harmful substances but they were at levels for which there are no known great health risks.The district issued the Navy a notice of violation for creating a public nuisance and contaminating the air.The Navy has yet to say whether the vessel will be repaired. 600

SAN DIEGO (AP) — It was a night of memorable debuts for the Arizona Diamondbacks.Merrill Kelly paused for a moment before making his first big league appearance at age 30."I took a minute before I threw the first pitch and took in the stadium, took in the surroundings, just so I can have that memory before I stepped on the rubber," the right-hander said. "Once I got going, once I stepped on the rubber, it was game time."Kelly threw six strong innings for the victory and benefited from an offensive outburst started by Adam Jones' leadoff homer to lead the Arizona Diamondbacks over the San Diego Padres 10-3 Saturday night.RELATED: 'Anchorman'-themed race debuts at San Diego Padres gameA few hours later, the bullpen gate opened and right-hander Jon Duplantier, 24, jogged in to throw his first big league pitches when he took over for Kelly starting the bottom of the seventh."I wasn't nervous jogging in. I was more nervous warming up," Duplantier said. "As soon as I walked through the door, hit the pad and took about three steps before it was like, 'OK, I'm not going to fall, I'm not going to trip,' because I've got big feet and every now and then the turf monster will get me, but he didn't get me today."Took about three steps and I just couldn't stop looking up, just taking it all in like everybody was encouraging me to do. It was just pure joy. I felt like a child, you know, like, 'Hey, go play, run free. Go play. These people are watching you.' I was just so happy," he said.RELATED: After nearly 30 years, Germany's San Diego Padres-themed bar closes"It was a special day for him and Jon, two guys making their major league debut," manager Tory Lovullo said. "You'd never suspect it by their mound presence, their poise and their ability to attack hitters."Padres rookie shortstop Fernando Tatis Jr. hit his first big league homer, a two-run shot in the sixth that landed at the base of the Western Metal Supply Co. building in left field.Kelly (1-0), who grew up in Arizona, joined the Diamondbacks on a two-year contract in December after spending four seasons with the SK Wyverns in Korea. That followed five seasons in the Tampa Bay organization. He became the first player with no big league experience to play in Korea and return directly to the majors.Kelly held San Diego to three runs and five hits while striking out three and walking two.RELATED: Manny Machado assumes the Padres' 'villain' role, but doesn't take it to heartKelly started strong thanks to his defense. Left fielder David Peralta made a diving catch of a liner by leadoff batter Ian Kinsler, and center fielder Ketel Marte made a sliding catch of Eric Hosmer's liner.San Diego didn't get a hit until Franchy Cordero, who entered in a double switch in the third inning, singled to right in the bottom of the inning. Cordero had an infield single in the fifth that hit off Kelly, who stayed in the game.Kelly faltered in his final inning, allowing Hosmer's double and Manny Machado's single before Franmil Reyes hit a sacrifice fly. With two outs, Tatis, the team's prized prospect and the son of the former big leaguer, drove the first pitch he saw for his first homer."I enjoyed it as soon as I hit it and it was a pretty decent walk around the bases," Tatis said. "Took that one out of the way, first one, here we go, a lot more to come."Matt Strahm (0-1) had a rough season debut for the Padres, allowing five runs and eight hits while walking two in just 2 2/3 innings. The left-hander is in the rotation this year after making five starts as an opener last year and 41 appearances overall as he was eased back from surgery on his torn left patellar tendon the previous season while with Kansas City."I was just getting a little too much plate and they were taking advantage of it." Strahm said. "They clearly read the scouting report that I'm aggressive with my fastball and jumped on it early, so I found myself pitching behind there a little bit."Jones, who played at San Diego's Morse High, homered to left on Strahm's third pitch, his third, and David Peralta added an RBI double. Eduardo Escobar hit an RBI single in the second and the Diamondbacks chased Strahm in the third on Nick Ahmed's sac fly and Alex Avila's run-scoring single.The Diamondbacks piled on with four runs in the fifth against Robbie Erlin, who allowed four hits before getting an out.GRAND CANYON BALLERSKelly is the fifth Diamondbacks player to play high school and college ball in Arizona, joining Jake Barrett, Tuffy Gosewisch, Cody Ransom and Ed Vosberg. Kelly grew up in Scottsdale and attended Desert Mountain High, Yavapai College and Arizona State.UP NEXTDiamondbacks: RHP Zack Greinke (0-1, 17.18) is scheduled to start Tuesday night. He's looking to bounce back from opening day, when he allowed seven earned runs in 3 2/3 innings in a 12-5 loss at the Los Angeles Dodgers.Padres: LHP Eric Lauer (1-0, 0.00) threw six shutout innings in an opening day victory against San Francisco. 4981
