PESHAWAR, Pakistan (AP) — Pakistani intelligence officials say they have evidence al-Qaida's second in command was in a house hit by a U.S. drone strike but they do not know whether he was killed.

U.S. officials have said they were targeting Abu Yahya al-Libi in Monday's strike in Pakistan's North Waziristan tribal area and were "optimistic" he was killed.

Pakistani intelligence officials said Tuesday militants and local residents reported al-Libi was in the house. The officials spoke on condition of anonymity because of the issue' sensitivity.

A local Taliban chief said al-Libi's guard and driver were killed, but the al-Qaida commander was not there. The Taliban commander spoke on condition of anonymity for fear of being targeted.
