An airstrike killed two suspected al-Qaida militants in Yemen on Friday while tribesmen with links to the group were believed to be behind an attack on an oil pipeline elsewhere in the country, Yemeni security officials said.
Officials and residents suspect that the strike in the southeastern province of Hadramawt was carried out by a U.S. drone. Washington considers al-Qaida in Yemen the group's most dangerous branch and has carried out drone strikes that have killed militants there before.
Yemeni security officials said the two men were killed while riding a motorcycle. The officials spoke on condition of anonymity because they were not authorized to speak to the media.
