"We will hunt you down": Biden vows retribution after Kabul attacks

President Biden vowed retribution for the complex attack in Kabul that killed 12 service members and injured 15 more at Hamid Karzai International Airport.

"We will not forgive. We will not forget. We will hunt you down, and make you pay," he said at the White House Thursday.

Mr. Biden, speaking for the first time since the American deaths were confirmed, said he has asked military commanders to develop plans to strike ISIS-K assets. The U.S. has "some reason to believe" they know who the responsible ISIS-K leaders are, he said. The president had warned earlier this week that the ISIS affiliate in Afghanistan, ISIS Khorasan or ISIS-K, posed a serious threat to the evacuations of Americans and vulnerable Afghans.
