and tax warning. the new change affecting millions of taxpayers. good evening. thanks for joining us on a saturday. i'm tom llamas. we begin with new bombings by president bashar al assad on his own people in that chemical attack. this as images are emerging of syrian jets taking off from the airbase targeted by u.s. tomahawk missiles. president trump defending and explaining the decision not to bomb the runways and tonight we hear from one of the most visible victims from the syrian attack. the father of baby twins killed by the chemical weapons. abc east alex marquardt leads us off tonight. >> reporter: tonight, the syrian airbase hit by the u.s. military back up and running, new photos showing syrian jets taking off less than

24 hours after the u.s. strike. the markings from the bombings seen on bunkers. images showing aircraft and bombed out fuel tanks and damage to aircraft shelters. but the runways untouched. tonight the president tweeting a defense. the reason you generally don't hit runways is that they are easy and inexpensive to quickly fix. the pentagon says it was from this base that a plane took off with the deadly nerve agent used in tuesday's chemical attack that killed more than 80 people. and that town bombed again today according to a watchdog group. >> there is irony here that it does appear that it's okay for mr. assad to blow up his people. it's just not okay to gas them. >> when president trump announced the strike he pointed to the children who were killed. >> it was a slow and brutal death for so many. even beautiful babies were cruelly murdered in this very

barbaric attack. >> perhaps no image more gut wrenching of this one of abdul hameem youssef hugging his two lifeless twins. he went house to house trying to rescue neighbors and family. many foaming at the mouth. he lost 25 relatives in the attack during which he fainted. >> translator: when i came to i asked for them he said. i told them hello darlings i took too long. i rescued everyone else but i couldn't rescue you. describing the moment the photo was taken youssef said i wasn't aware of anything. i thought they were alive. i was expecting them to hug me back. >> that father's story and the images so devastating. alex joins us live. the big question, will syria respond to the u.s. attack and do we know if today's new bombing by syria of that town

where the chemical attack occurred was that retaliation? >> reporter: it's unclear whether that syrian attack was in direct response to the american strike which president assad has called an unjust act of aggression but we are seeing the reaction. a defiant assad saying we are going to continue carrying bombing runs and launching our planes from the base that you just struck. tom. >> alex, thank you. digging deeper into the decision around that strike plus the brewing civil war inside the west wing between two of the president's top aides. abc's david wright reporting from west palm beach tonight. >> reporter: tonight the president still insists the tomahawk missile strike was an unqualified success. tweeting out, "congratulations to our great military men and women for representing the united states, and the world so well." not long ago trump was reluctant to intervene in syria.

we don't want world war iii over syria. >> back when president obama wanted to punish syria for a previous chemical attack. trump tweeted what will we get for bombing syria besides more debt and a long term conflict. obama needs congressional approval. trump informed congress after the missiles were launched. george stephanopoulos asked secretary of state rex tillerson if the strike signals a change in u.s. policy. >> this strike was related solely to the most recent horrific use of chemical weapons against women, children and as the president said even small babies. we are calling on bashar al assad to cease the use of the weapons. other than that there is no change to our military posture. >> even as the president was juggling two foreign issues, china and syria. he had to intervene in a conflict among his own senior staff.

chief strategist steve bannon and son-in-law jared kushner were allies during the campaign but sources say lately the two have clashed with kushner pushing for greater engagement with the world, bannon for the strategy america first. abc news learned the day after these photos were taken at mar-a-lago kushner and bannon sat down friday in an attempt to settle their differences. chief of staff reince priebus also attended the meeting but white house officials deny any imminent shakeup. >> david, the president is dealing with syria, a new supreme court justice, this public feud between aides is the last thing he needs right now? >> reporter: that's right. this is a huge moment for the president. you have got a china summit that came off without incident. missiles that hit their targets in syria and a new supreme court pick to be sworn in on monday. the last thing the white house wants is talk of infighting, tom.

>> david, thanks. there'll be much more on the interview with secretary of state tomorrow on "this week." turning to sweden. a country still in shock over a truck attack mowing down pedestrians in the capital. a 39-year-old suspect under arrest and investigators examining a device they say was found inside the truck. the country's prime minister paying his respects at a ma make-shift memorial. terry moran with the latest. >> reporter: it was sweden's moment of terror. a stolen beer truck suddenly transformed into a massive weapon, barreling down a crowded shopping street. >> there were bodies on the ground everywhere, and a sense of panic. >> reporter: and today, we know the man authorities say was behind the wheel, seen here in grainy security camera images released while he was on the run after the attack. he's 39 years old, originally from uzbekistan in central asia, known to security services here as a possible islamic extremist,

revolution. it's time for change. >> reporter: inside, investigators say plans of a brutal attack and disparaging comments about the president all in a 161-page anti-government manifesto. >> address. leaving. >> reporter: police say you can see jakubowski in this photo stealing 16 firearms from a gun shop before setting his car on fire and disappearing. authorities are calling him armed and dangerous. investigators using dogs, planes and more than 150 officers to search. tonight his neighbor on edge. >> i just want this to end. i just -- i want to feel safe in my home again. >> reporter: the fbi is now offering a $10,000 reward for information leading to jakubowski's arrest. they're hoping he turns himself in but asking for the public's help. tom. >> still so many questions about his motive. thanks eva. breaking news.
