canadian prime minister justin trudeau says the shootdown happened over the yukon territory. in a tweet tonight trudeau said he ordered norad to take down the object that had violated canadian air space. cbs's christina ruffini is at the white house with the latest. christina, good evening. >> reporter: good evening, adriana. in another tweet just a little while ago trudeau says he also spoke with president biden and he thanks norad for keeping watch. he says canadian forces are going to recover and analyze the wreckage of the object but american forces still haven't recovered the wreckage of the object they shot down on friday. nor has the department of defense provided any more details as to what exactly it was. >> success. >> reporter: the f-22 fighter jet shot down the unidentified floating object about the size of a small car off the frozen coast of alaska friday. on the order of the president. >> that's the best description we have right now. we do not know who owns it. >> reporter: the white house says the latest aerial intruder

was floating at an altitude about 40,000 feet and had no maneuverability, posing a threat to civilian aviation. >> we have no further details about the object at this time, including any description of its capabilities, purpose or origin. >> reporter: the u.s. military is scouring the frozen arctic for the wreckage while also searching off the carolina coast for the payload of a huge chinese surveillance balloon shot down last week. >> we made sure that we're buttoned down and movement was limited and communications were limited. >> reporter: in an exclusive interview defense secretary lloyd austin told cbs's david martin all bases where u.s. nuclear forces are located were ordered to cover up as the chinese airship passed over the united states. initially spotted above montana, the balloon did not loiter over any other locations, instead floating across the u.s. as fast as the wind would carry. >> the balloon is completely destroyed. >> reporter: but when austin tried to call his chinese counterpart after the shootdown

he says they essentially left him on read. >> i put in the request for a all and they did not accept that request. >> reporter: now, department of defense sources tell cbs news one of the reasons they've been unable so far to get to that object that was shot down in alaska is because they're being hampered by conditions. adriana, the recovery zone is minus 45 degrees. >> christina ruffini, thank you. to earthquake-ravaged turkey and syria now. tonight the death toll from monday's catastrophe soared again. at least 28,000 are now reported dead. but amid the ruins and despair today new stories of survival. multiple people were rescued today. among them this 12-year-old boy named muhammad. his rescue after nearly a week buried alive overwhelming search crews. cbs's imtiaz tyab is in turkey tonight with the latest. >> reporter: adriana, good evening. well, six days after the devastating earthquakes and the

hopes of finding survivors is dwindling by the minute. but rescue workers remain determined to try and save anyone they can. they painstakingly pick through the rubble, desperately searching for survivors. then their worst fear. one emergency worker was moderately injured. the rest unharmed. unimaginable luck in a place with so little. in hard-hit adana babies and small children receive treatment at a hospital in the southeastern city. most were plucked from the ruins by rescue workers. but lost in the chaos were their names. with no one yet to claim them, the fear now is the earthquake has robbed these babies of their parents and quite possibly their identities too. "we know what area she was found in and how she got here," dr. keslin says, "but don't have any address."

for other survivors they grieve for those they've lost wherever they've been buried, as more and more fresh graves are dug up in anticipation of mass burials. the scale of monday's 7.8 magnitude quake and its many aftershocks continue to defy comprehension. so too do the numbers. at least 6,000 buildings have collapsed. 900,000 people need urgent shelter. and around 5 million have been displaced from their homes. aid has come in from 45 countries, including the u.s. but for badly hit syria, just two convoys have made it into northwestern idlib province, the last remaining rebel-held territory in a country deeply scarred by over a decade of civil war. it's a grinding conflict 6-year-old musa was born into. he was found after four days trapped under the rubble in the southern town of jindires. in his short life musa has survived war and now this earthquake.

but with so little help on the way it's hard to know what future if any he has. now, the u.n. is warning the death toll here could double, bringing it to over 50,000 dead, adriana. easily making this the worst disaster this part of the world has seen in over a century. >> hard to comprehend. imtiaz tyab, thank you for your reporting. in this country a pipeline that supplies gas and diesel fuel to some big cities in the west is expected back online tonight. but not before its shutdown prompted some panic buying at the pump. cbs's elise preston has the latest on what led to the interruption. elise, good evening. >> reporter: good evening to you, adriana. the company that owns the pipeline says it will be fully operational tonight. now, the problem began thursday at a pump station in long beach, california, prompting the operator of the pipeline that fuels parts of los angeles, phoenix and las vegas to shut it down.

this is what happened. drivers across las vegas flocked to gas stations hoping to fill up. some waiting for an hour. panic buying began as nevada's governor declared a state of emergency last night in clark county. the state hoped to preserve supplies for the more than 2 million residents. now, the pipeline, owned by kinder morgan, runs more than 565 miles from refineries in california to nevada. officials say the shutdown did not impact the supply of gas, just its delivery. the company says the leak was contained at the pump house and it is investigating what caused it. we reached out to several agencies. there's no word yet on any environmental damage. adriana? >> elise preston, thank you. after two weeks of nonstop hype the philadelphia eagles face the kansas city chiefs in super bowl lvii tomorrow. even though the game's been played for more than half a century, this year there are several notable firsts. kris van cleave is outside the

stadium in glendale, arizona. good evening, kris. >> reporter: good evening. the time for talking, adriana, is pretty much done. you'll have one more night of glitz and glamour. the teams are done practicing. the fans, the players, everyone's ready to get this show started. after two weeks of hype it's almost time for football on the world's biggest stage. >> it's just a big build-up to the game. everybody can't wait. >> reporter: chiefs all-pro punter tommy townsend. >> i'll just kind of be standing there throughout random days and i'll blink my eyes and be like how did i get here? >> reporter: super bowl lvii will mark the first time both teams are led by black quarterbacks. for the eagle's jalen hurts it's also his first super bowl. >> i see it as an opportunity to honor everyone that has come before me. >> the guys that came before me and jalen and set the stage for this, and now i'm just glad that we can kind of set the stage for guys that are -- kids that are coming up now. >> reporter: jason and travis kelce will be the first brothers to play on opposing teams in a

super bowl. >> is all this attention surreal? >> it's a little crazy. i never turn down a chance to talk about my kids. >> reporter: their very proud parents ed and donna. >> the thing that i'm upset about is i didn't buy a lottery ticket. i mean, to go from high school to college, college to the pros, and then to both be in the super bowl together, it's like what are the odds on that? >> reporter: another first will happen before the game even starts. at the controls of the four-fighter flyover will be seven women, recognizing 50 years of female navy aviators. >> this is a great way to honor the women that have come before us. >> reporter: as many as a million people are flocking to arizona leading up to super bowl sunday. regardless of what uniform the fans are wearing, they agree on one thing. they are very excited for this game to happen. >> we are ready. >> it's been a long two weeks. so we're definitely ready and looking forward to it. >> this is my first time. so actually enjoying the nfl experience and an nfl stadium is

like insane. >> reporter: now, when it comes to security, nearly 1,000 police from state, local and federal agencies will be working this game. anything or anyone going into the stadium behind us here will be screened. adriana? >> kris van cleave, thank you. the mayor of canada's largest city, toronto, has resigned after an affair with a former staffer during the pandemic. john tory stepped down friday night. tory was known as a straight-laced conservative first elected in 2014 to restore respectability to the office after the previous mayor's term ws marred by drinking and cocaine use. there's new concern along the northern border with canada. the number of illegal crossings is on the rise, the trip often treacherous. john lauritsen of our minneapolis station wcco takes us to the border near pembina, north dakota. >> reporter: it is the longest international border in the

world, most of it undefended and desolate. and crossing can be treacherous, even deadly if you're trying to avoid detection. >> it was out there where the family was found. >> reporter: david marcus is a u.s. border patrol agent in grand forks, north dakota. >> the air temperature was around 9 below zero. the wind chill was close to 30 below zero. and then the wind was blowing real bad. so you're not going to survive real long in that. >> there was three of them. i didn't he see the incident. >> oh. >> a little baby and probably 9 or 10-year-old and their father. >> reporter: they were a family of four from india. the children just 11 and 3. they flew into toronto, then froze to death trying to walk from manitoba into minnesota. their deaths haven't deterred others. more are taking the risk. along this 860-mile stretch of border that the grand forks sector patrols the only real barriers are snow and trees. this year they've seen a 500% increase of arrests for people trying to cross into the u.s.

illegally. >> it's not uncommon to see negative 40 here. we're also filling gaps -- >> reporter: anthony good runs u.s. border patrol operations from wisconsin to north dakota. >> personally it breaks my heart, right? no one wants to see another human being suffer. >> reporter: illegal crossings are up all along the northern border. in one sector they're up more than 700%. and increasingly like on the southern border people are being smuggled by human trafficking rings. >> the smugglers do not care about their lives at all. all they care about is the money. somebody that might smuggle human beings will also on their way back smuggle guns into canada or smuggle drugs with these people into the united states. >> there are always going to be people that are going to be willing to risk it all when they have nothing to lose. >> reporter: matt dearth is an attorney representing a man charged with smuggling eight people across the northern border last year. >> they're fleeing persecution. there's a lot of drug and gang-related violence.

there is ecological disaster. the clearest most safe place they can go with the best chance of a successful life is going to be in the united states. >> reporter: apprehensions here are still a fraction of those on the border with mexico. but they are growing at a much faster rate. and with winter so unforgiving any one could be fatal. john lauritsen, cbs news, pembina, north dakota. straight ahead on the "cbs weekend news," north korea rolls out a deadly arsenal of long-range missiles. a crime of catalytic proportions as thieves disable the wienermobile. and it's super sunday for advertisers too. we'll show you the best new ads even before the game. >> i'm ben stiller. my job as an actor is making you believe what you're seeing -- s. my job as an actor is making believe what you're seeing -- astepro starts working in 30 minutes. so you can
