The wild ride on Wall Street just got crazier.The Dow dropped about 345 points, or 1.4%, on Tuesday, completely reversing a 244-point gain from early in the day. The selloff followed Monday's 670-point spike.The Nasdaq plunged nearly 3% -- wiping out nearly all of Monday's huge gains for the tech sector. The Nasdaq is now up just 1.5% on the year.Facebook, Twitter, Tesla and Nvidia all fell sharply. Netflix tumbled 6%, its biggest decline in two years."We started bleeding when large tech got hit hard," said Art Hogan, chief market strategist at B. Riley B.Investors poured money into bonds Tuesday. The 10-year Treasury yield slipped to 2.77%, the lowest since early February.But the sinking yields also narrowed the closely-watched gap between short and long-term rates, known as the yield curve."That has persistently been a signal of an economic slowdown," said Hogan. "I don't think that's the case here."A "flattening" yield curve also makes it harder for banks to make money on the difference between what they lend out and pay interest on. Bank of America, Wells Fargo and PNC fell more than 2% apiece.The-CNN-Wire 1135

The Supreme Court said on Monday that it will stay out of the dispute concerning the Deferred Action for Childhood Arrivals program for now, meaning the Trump administration may not be able to end the program March 5 as planned.The move will also lessen pressure on Congress to act on a permanent solution for DACA and its roughly 700,000 participants -- undocumented immigrants who came to the US as children.Lawmakers had often cited the March 5 deadline as their own deadline for action. But the Senate failed to advance any bill during a debate earlier this month, and no bipartisan measure has emerged since.  627

The US believes that Ibrahim al-Asiri, a master al Qaeda bombmaker, is dead.The Saudi Arabian native was the mastermind behind the "underwear bomb" attempt to detonate a flight above the skies of Detroit on Christmas Day in 2009.A senior US official expressed "confidence that he was killed."Two US officials told CNN al-Asiri was killed by a CIA drone last year. The CIA is not commenting on his fate.CNN reported last week that al-Asiri may have been killed in Yemen last year, according to a UN team that tracks terrorist groups.Counterterrorism analysts say there should be significant skepticism over al-Asiri's possible demise for one major reason: His group, al Qaeda in the Arabian Peninsula, has not released any statement acknowledging his death, nor a eulogy celebrating his martyrdom.Al-Asiri is widely credited with perfecting miniaturized bombs with little or no metal content that could make it past some airport security screening. That ability made him a direct threat to the US, and some of his plots had come close to reaching their targets in the US.In addition to the "underwear bomb" attempt, al-Asiri was behind the so-called "printer bomb" plot. That plan saw him send explosive devices inside printers to the US. The two packages were being shipped from Yemen through Dubai and the UK in October 2010.Both were addressed to synagogues in Chicago.Al-Asiri appeared to have taken on a more public-facing role within al Qaeda in the Arabian Peninsula in recent years, including purportedly recording a speech the group released in 2016.The most recent public statement attributed to him was a written speech released by the group on September 12, 2017, to coincide with the 16th anniversary of the 9/11 terrorist attacks. The speech promised an ongoing war against the United States.CNN cannot independently verify he authored these statements.Few expect al-Asiri's expertise to die with him. Officials believe he trained a number of apprentices. And since 2014, US officials have been concerned that bomb-making expertise built up by al Qaeda in the Arabian Peninsula has migrated to other groups, including al Qaeda operatives in Syria.Meanwhile, ISIS is among the terrorist groups that have worked to develop laptop bombs, prompting large electronics to be temporarily banned in the cabin on certain flights to the United States and the UK from the Middle East last year. 2414

The walk to school turned terrifying for a Rochester, Michigan teen who says he was shot at after he stopped to ask for directions.Fourteen-year-old Brennan Walker missed the bus and tried to walk to school, but got lost after he couldn't remember the route.The freshman wasn't hit, as the shot missed him as he ran away.The situation began when Walker's alarm didn't go off. After missing his bus, he thought he could walk the roughly 4 miles to school.Once he became lost, he stopped at a home and knocked."I knocked on her door a few times and she came down yelling at me before I could say anything and she thought I was trying to break into her house," he said. "I was trying to explain to her that I wanted to get directions to go to my school. I told her no, I go to Rochester High I’m just looking for directions to Rochester High."Walker and his mother, Lisa, say the security video from the home shows the woman then yelled for her husband."The man of the house came down, pretty much just grabbed the shotgun to shoot at my son," says Lisa Walker."I saw it. I saw him holding it like this through the window and I guess I put my hand up, I don’t really remember, and I started to run," Brennan Walker says. "I looked back behind me I saw him aiming at me and I turned back. I turned back and I heard the gunshot. And I tried to run faster."The man has been taken into police custody."If someone is running from your house and chase them outside and shoot at them, you’re going to have criminal charges coming from us," Oakland County Sheriff Michael Bouchard said.Both Walker and his mother believe race was a factor in the incident."After watching the video and hearing the wife say 'why did these people choose my house' I knew it was racially motivated. I don't know what other these people she could possible have been talking about. He was by himself," Lisa Walker said."I didn’t want to believe that that type of stuff could happen here," said Brennan, who said he is just trying to process the shock of what happened."I don't, I don't know how you process getting shot at for asking for directions," he says. 2159
