US Central Command also confirmed that Badawi was killed in a precision strike in Marib province of Yemen on Jan. 1.

US forces confirmed the results of the strike following a deliberate assessment process, according to the Twitter account of US Central Command.

Badawi was believed to be one of the principal architects of the bombing attack against the US Navy destroyer USS Cole in Yemen's Aden harbor in October 2000.

The suicide bombing attack, which carried out by a small boat loaded with explosives, left 17 US sailors dead, 39 injured.
