WASHINGTON (AP) — President Joe Biden vowed Thursday to complete the evacuation of American citizens and others from Afghanistan despite the day’s deadly suicide bomb attack at the Kabul airport. He promised to avenge the deaths of 13 U.S. service members killed in the attack, declaring to the extremists responsible: “We will hunt you down and make you pay.”

Speaking with emotion from the White House, Biden said the Islamic State group’s Afghanistan affiliate was to blame for the attacks that killed the Americans and many more Afghan civilians.
