A US air strike in Afghanistan has killed a high-ranking al Qaeda operational commander, the Pentagon said on Friday. The Pentagon named the target of the strike as Abu Khalil al-Sudani, saying he was killed in a July 11 strike in the Bermal district of Afghanistan's Paktika province. In a statement, the Pentagon said he was head of al Qaeda 'suicide and explosives operations' and was linked to external attack plotting against the United States.
