Jamal al-Badawi, the al-Qaeda militant behind the attack on the USS Cole in Yemen in 2000, died in a US air strike, President Donald Trump has confirmed.
"Our great military has delivered justice for the heroes lost and wounded in the cowardly attack on the USS Cole," Mr Trump tweeted.
US defence officials said a "precision strike" was carried out last Tuesday east of the Yemeni capital, Sanaa.
Badawi was believed killed but that could not be confirmed at the time.
Seventeen US sailors were killed and at least 40 people were wounded in the attack which happened as the destroyer was refuelling in the port of Aden.
