Pakistani intelligence sources say a U.S. drone strike in northwest Pakistan has killed a senior militant with links to al-Qaida.

Badar Mansoor was killed in the attack early Thursday at a house in Miran Shah, the main town in Pakistan's North Waziristan tribal agency. His death was confirmed by members of the Pakistani Taliban.

Officials say Mansoor led a group of Taliban fighters in the region and had close ties to al-Qaida. He was allegedly involved in a number of attacks throughout Pakistan.

Four other militants were also killed in the missile strike.

It was the second such attack in northwest Pakistan in as many days.

Pakistan's northwest border region is home to both Pakistani and Afghan Taliban fighters.
