TIJUANA, Mexico (AP) — Migrants approaching the U.S. border from Mexico were enveloped with tear gas Sunday after a few tried to breach the fence separating the two countries.U.S. agents shot the gas, according to an Associated Press reporter on the scene. Children were screaming and coughing in the mayhem.Honduran migrant Ana Zuniga, 23, said she saw migrants open a small hole in concertina wire at a gap on the Mexican side of a levee, at which point U.S. agents fired tear gas at them."We ran, but when you run the gas asphyxiates you more," she told the AP while cradling her 3-year-old daughter Valery in her arms.RELATED: Caravan marches toward US border in show of forceMexico's Milenio TV also showed images of several migrants at the border trying to jump over the fence. Yards away on the U.S. side, shoppers streamed in and out of an outlet mall.U.S. Border Patrol helicopters flew overhead, while U.S. agents held vigil on foot beyond the wire fence in California. The Border Patrol office in San Diego said via Twitter that pedestrian crossings have been suspended at the San Ysidro port of entry at both the East and West facilities. All northbound and southbound traffic was halted.Earlier Sunday, several hundred Central American migrants pushed past a blockade of Mexican police who were standing guard near the international border crossing to pressure the U.S to hear their asylum claims. They appeared to easily pass through without using violence, and some of the migrants called on each other to remain peaceful.RELATED: Woman with child injured while scaling border fenceThe migrants carried hand-painted American and Honduran flags and chanted: "We are not criminals! We are international workers!"A second line of Mexican police carrying plastic riot shields stood guard outside a Mexican customs and immigration plaza.That line of police had installed tall steel panels behind them outside the Chaparral crossing on the Mexican side of the border.Migrants were asked by police to turn back toward Mexico.More than 5,000 migrants have been camped in and around a sports complex in Tijuana after making their way through Mexico in recent weeks via caravan. Many hope to apply for asylum in the U.S., but agents at the San Ysidro entry point are processing fewer than 100 asylum petitions a day.Irineo Mujica, who has accompanied the migrants for weeks as part of the aid group Pueblo Sin Fronteras, said the aim of Sunday's march toward the U.S. border was to make the migrants' plight more visible to the governments of Mexico and the U.S."We can't have all these people here," Mujica told The Associated Press.Tijuana Mayor Juan Manuel Gastelum on Friday declared a humanitarian crisis in his border city of 1.6 million, which he says is struggling to accommodate the crush of migrants.U.S. President Donald Trump took to Twitter Sunday to express his displeasure with the caravans in Mexico."Would be very SMART if Mexico would stop the Caravans long before they get to our Southern Border, or if originating countries would not let them form (it is a way they get certain people out of their country and dump in U.S. No longer)," he wrote.Mexico's Interior Ministry said Sunday the country has sent 11,000 Central Americans back to their countries of origin since Oct. 19. It said that 1,906 of them were members of the recent caravans.Mexico is on track to send a total of around 100,000 Central Americans back home by the end of this year.RELATED: 3488

Their youthful brains were developing normally, with no signs of developmental, psychological or neurological problems. None had ever had a concussion. But by the end of a single football season, 24 children between the ages of 9 and 18 who had more frequent impacts to the head showed signs of damage to brain development, new research says."Repetitive head impact exposure may have a cumulative effect in the rapidly developing brains of youth and high school football players," said study co-author Gowtham Krishnan Murugesan, a radiology research assistant at UT Southwestern Medical Center in Dallas, adding that the results mirror other recent findings.The study outfitted 60 youth and high school football players who had no history of head trauma or developmental issues with a head impact telemetry system that measures the magnitude, location and direction of impacts to the head. The researchers were not looking at whether the impact resulted in a concussion, only that impact occurred.The children were sorted into two categories: high cumulative head impact players (24) and low cumulative head impact players (36).Before beginning to play, each child had a resting state functional scan, known as an fMRI; the scans were repeated at the end of football season. The researchers were trying to see how exposure to repetitive hits affects the normal "pruning" process in the brain that occurs during adolescence."Pruning is an essential part of brain development," Murugesan said, comparing the process to how a tree needs to have dead or unneeded branches cut to keep it healthy and allow it to grow."Disruption in normal pruning has been shown to be related to weaker connections between different parts of the brain," he said.After comparing the functional MRI results to the player's level of impact, the researchers found that youth in the high-impact group had damage to their brains' pruning process after one season."Our study has found a significant decrease in gray matter pruning in the frontal default mode network, which is involved in higher cognitive functions, such as the planning and controlling of social behaviors, " Murugesan said.Although the "teenage years are a critical time for brain development, brain remodeling or synaptic pruning, this was a short-term study and did not follow the players longitudinally over several years. We don't really know the full application," said Dr. Julian Bailes, director of neurosurgery and co-director of the NorthShore University HealthSystem Neurological Institute, who was not involved in the research.Weill Cornell neurologist Dr. Richard Isaacson, who was also not involved in the study, called the research "early" and said the results don't necessarily "translate to a clinical or cognitive outcome." More research is needed to see whether the decline in brain pruning permanently affected the child's cognitive function or whether the brain's natural plasticity allowed it to repair itself."I would call this a pilot study," Isaacson said. "The call to action would be that we need more robust longitudinal studies with a pre- and a post-assessment of more than brain imaging. The study should also measure cognitive and neurological function and look for changes."As we learn more about the issue, Isaacson said, parents should do everything they can to limit contact in sports, "especially in practice before games, where studies show the majority of contact occurs." 3464

Three Denver police officers have been suspended after three separate incidents this year of arrestees being forgotten in temporary holding cells overnight. Policy requires desk officers to check on people detained in holding cells every 30 minutes and to notify a supervisor if someone has been held there for more than an hour. The holding cells are supposed to be temporary stops for arrestees before they can be transported to the city jail. Yet one woman, in custody for an unpaid traffic ticket, sat in a sparse police department holding cell for nearly 13 hours. Handcuffed to a bench, Victoria Ugalde could not reach the toilet for much of the time and had no option but to urinate on the floor.  "They forgot about me," Ugalde said. "I was looking in the camera, I was [saying] 'Can anybody help me?' And then, nobody."The desk officer who was supposed to check on Ugalde admitted he failed to notice she was there because he was wrapped up in reading a book, titled "Emotional Intelligence 2.0."He served a three-day suspension and is back on the job.The seemingly strange scenario played out twice more this year, and the police department is weighing policy changes to prevent it from happening again. "It should not have occurred," said Jess Vigil, deputy director of the Denver Department of Safety. "It doesn’t sit well with me and it doesn’t sit well with the department.”"I cried a lot"Victoria Ugalde had her driver's license revoked after a DUI arrest in 2003. She said she quit drinking after that arrest. In 2013, a police officer caught her driving with her license still revoked and cited her. Ugalde admits she did not go to court because she could not pay, so the judge issued a warrant for her arrest. 1785
