welcome to "world news tonight." we're tracking the arctic assault. heavy snow and treacherous travel. a plane skidding off the taxiway. hundreds of flights canceled. the trouble coming for the morning commute. and the bitter cold on the way. the russian connection? president-elect trump saying there's no way hackers backed by russia tried to help him win. >> i think it's ridiculous. >> but tonight, lawmakers from both sides of the aisle calling for an investigation. wave of terror. two deadly blasts at a turkish soccer match. and the new attack at egypt's main christian church. most of the victims, women and children. gps fail? a family stranded in a snowstorm deep in the woods. why their gps took them on a road to nowhere. and, lifesaver.

the incredible video. a frantic mother scrambling for help. her baby not breathing. and the deputy who happened to know just what to do. good evening. thanks for joining us on this sunday. i'm tom llamas. we begin with the extreme weather targeting much of the country, winter weather alerts in 17 states, from illinois to massachusetts. the plane sliding off the runway. i-75 shut down with dozens of vehicles piled up, and this crash sending up a 14-foot wall of flames. and there's even colder weather ahead. the forecast in a moment. but first, alex perez, starting us off from snowy chicago tonight.

>> reporter: this delta flight caught in a snowy blast. >> and delta 724, we just went into the ground. >> reporter: this delta flight skidding off the runway after landing in detroit. passengers forced to evacuate out of the plane's rear hatch. hundreds of flights cancelled or delayed, as the windy city gets a winter wallop. >> i've never seen it like this in december. >> reporter: roads from minnesota to new york, treacherous. in minneapolis, this car bursting into flames after sliding on slick roads. and outside of flint, michigan, that massive 33-car pileup closing a section of i-75 for hours. >> we got hit in each direction. we were spun around,

opposite direction. >> reporter: tonight, authorities begging drivers to stay off the roads. >> we want the public to ask themselves a simple question. is this trip really necessary? >> reporter: this is the second wint wint winter wallop for millions in just days. and more is on the way right now. all of the snow will make for a nightmare morning commute. and temperatures are about to plunge. tuesday in chicago, it will feel well below zero. tom? >> alex, thank you. and the snow is also falling in new york city. let's go to rob marciano with more. >> reporter: the snow reaching all the way to new york and the northeast cities. this is a large but thankfully fast-moving system. but from i-70 north, it's difficult moving.

means the snow should turn into rain tomorrow. but northward into new england, it will be mostly snow. 6 to 10 inches from detroit, new york, and new england. and here comes the big cold. tuesday, 20 below across the dakotas, and below freezing windchills in chicago for 24 hours. and the really cold stuff gets into the northeast on friday. tom? >> rob, thank you. let's turn to politics now. members of congress from both parties are calling for an investigation as to whether russia tried to influence the american elections. mr. htrump has his doubts.

tonight, new recoporting on whon the trump family may be moving to washington. here's mary bruce. >> reporter: tonight, donald trump is digging in, blasting a "new york times" report that russia int russ russia interfered with the election. >> i think the democrats are bringing it up because they lost a big election. >> reporter: news that both democrats and republicans were targeted, but only information hacked from democrats was made public. trump still questions if russia was involved at all, even after 17 u.s. intelligence agencies directed it. tonight, a bipartisan

calling for an information. trump's recent comments are raising serious questions about whether he trusts u.s. intelligence. and trump admits he's not receiving the classified presidential daily briefings. at least not every day. >> i get it when i need it. i don't have to be told -- i'm a smart person. i don't need to be told the same thing every single day for the next eight years. >> reporter: trump's secretary of state will inherit the complex relationship with russia. and trump's pick, rex tillerson. trump says the ties are a good thing. >> a great advantage, he knows many of the players. >> reporter: no announcement has been made yet, but today trump tweeted that tillerson is a world-class deal maker.

trump plans to leave his business in total, but his children will not. >> my executives will run it with my children. it's a big company, a great company. but i'm going to have nothing to do with management. >> and we'll get more details on thursday. mary, we know that melania and barron will move to washington with the start of the school year, and others are coming? >> reporter: yes, ivanka and her husband are planning a move. tom? >> mary, thank you. overseas now, the grim aftermath of a terror attack in istanbul, turkey. two powerful bombs. a camera capturing one of those

on the walls." this man says. "everything was broken." outside, the outrage and anger erupting. protests against terrorism, demanding national unity. egypt's president sisi is declaring three days of mourning, saying a religious war is being waged. vowing to hunt down the attackers. tom? >> lama, thank you. we head to nigeria tonight, a religious celebration ending with at least 160 people dead in a building collapse. the roof crashing down as it celebrated the church's new bishop. workers had rushed to finish the construction. and reports are that the roof gave way. and the trial in new orleans, closing arguments in the shooting death of former nfl star, will smith. here's phillip

>> reporter: prosecutors calling the road rage shooting an execution. jurors hearing closing arguments in the killing of former new orleans saints star, will smith. smith's wife, struck by the gunfire, too. >> my leg has been shot! >> reporter: speaking in his own defense, hayes told jurors he opened fire fearing for his own life. i know for a fact i was going to get shot, hayes said. claiming he heard a gunshot before pulling the trigger. police say a gun found in smith's car was not fired. >> the testimony has been contradicted by third-party witnesses and by the forensic evidence. >> reporter: former teammates like drew brees showing support throughout the trial. with closing arguments wrapped up, deliberations are set

predator. >> reporter: now, more than four months later, the dna found at the scene has turned up no matches in state or national databases. the district attorney asking to authorize familial dna searching. >> we have all investigative steps that have been exhausted. and this is the next logical move. >> reporter: it's already done in at least nine states, including california. where police say it led them to the serial killer known as the grim sleeper. 25 years after the murder spree began, investigators were able to partially link dna to his son, helping investigators hone in on the killer himself. but civil liberty groups call it an invasion of privacy.

privacy. >> reporter: the states now reviewing the d.a.'s request. and tonight, the family tells us, this needs to be done. not just in their case, but for all victims. tom? >> marci, thank you. next to a house fire so intense, it melted the siding off of a nearby home. tearing through a house with eight sleeping people inside. two of them jumping from a third-floor window just before the home collapsed. the 72-year-old homeowner died in the blaze. and desperate moments for a mother whose baby suddenly stopped breathing, and the moment that changed their lives. here's adrienne bankert. >> reporter: tonight, a frightening lesson on the importance of cpr, playing out in a florida dmv

>> reporter: tom, this was a case of right place, right time. deputy donaldson wasn't even scheduled to work that day. he was filling in for another officer. it's certainly a shift that he and this family will never forget. >> thank you. and there's much more still ahead on "world news tonight" this sunday. the giant tree suddenly slamming down on to a major highway. crushing a car. so, how can anyone survive this? plus, gps taking an unsuspecting family on a treacherous and harrowing ride. you need to see this story. and why all the excitement for this student and his entire school? their big moment, all caught on camera. stay with us. my friends think doing this at my age is scary. i say not if you protect yourself. what is scary? pneumococcal pneumonia. it's a serious disease. my doctor said the risk is greater now that i'm over 50!
