WASHINGTON — An American airstrike in Yemen last week killed one of the suspected plotters of the deadly Qaeda bombing of the United States Navy destroyer Cole in 2000, President Trump and military officials confirmed on Sunday.

On Friday, the military’s Central Command said it had conducted a strike on Tuesday in the Marib Province of Yemen that targeted the militant, Jamal al-Badawi, but added that it was still assessing whether he had been killed. By Sunday, the military was confident that Mr. Badawi was dead, Capt. Bill Urban, a spokesman for the command, said in an email.

“Our GREAT MILITARY has delivered justice for the heroes lost and wounded in the cowardly attack on the USS Cole,” Mr. Trump tweeted on Sunday before flying to Camp David for meetings with White House staff. “We have just killed the leader of that attack, Jamal al-Badawi. Our work against al Qaeda continues. We will never stop in our fight against Radical Islamic Terrorism!”
