QUETTA, PAKISTAN – The family of a driver who was killed alongside Taliban chief Mullah Akhtar Mansour in a U.S. drone strike in Pakistan has filed a case against U.S. officials, seeking to press murder charges, police said Sunday. Mansour had entered Pakistan from Iran using a false name and fake Pakistani identity documents on May 21, when his car was targeted by a U.S. drone. The driver, who was also killed, was later identified as Mohammed Azam. The police filed a case on behalf of Azam's family, police official Abdul Wakil Mengal said. It was not immediately clear what legal avenues the family can realistically pursue.

A DNA test has confirmed that Afghan Taliban leader Mullah Akhtar Mansour was killed in a U.S. drone strike, Pakistan's interior ministry said Sunday, as the family of a driver killed in the strike sought legal action. A DNA sample from one of the men killed in the U.S. drone attack was successfully matched with a close relative of Mansour, the interior ministry statement said. American and Afghan officials had already confirmed Mansour's death, but Islamabad had declined to do so before the DNA test results. Mansour had entered Pakistan from Iran using a false name and fake Pakistani identity documents on May 21, when his car was hit by the U.S. missile. On Sunday, the family of his driver -- identified as Mohammed Azam -- filed a police case against unknown U.S. officials, seeking to press murder charges against them, police officer Abdul Wakil Mengal said.

Supporters of the slain Taliban chief have held funeral prayers across Pakistan for Mullah Akhtar Mansour, killed in a U.S. drone attack last week. Some 400 Jamaat-ud Dawa members held the ceremony Friday in the northwestern city of Peshawar. Similar ceremonies were also held in Quetta, Hyderabad and Karachi. Jamaat-ud Dawa is a terror organization widely believed to be front group for Lashkar-e-Taiba, blamed for the 2008 attacks in the Indian city of Mumbai. The funeral prayers took place even though Mansour's body is still in the hands of Pakistani authorities for DNA testing.
