Pakistani officials say a Filipino militant wanted by the United States is believed to have been killed in an American drone strike earlier this month.

Two military intelligence officials said Thursday that Abdul Basit Usman was killed on Jan. 14 close to the Afghan border.

They cited militant informers as the source of the information. They spoke on condition of anonymity because of the sensitivity of their work.

Filipino officials in the Philippines and Pakistan said they had no information on the attack.

The U.S. State Department's list of most-wanted terrorists identifies Usman as a bomb-making expert with links to the Philippines-based Abu Sayyaf militant group and the Southeast Asian Jemaah Islamiyah network.
