ISLAMABAD (AP) — Pakistan's government is meeting with senior U.S. officials to discuss the fallout from a May 21 drone attack that killed Taliban chief Mullah Akhtar Mansour, while the family of the taxi driver who died alongside Mansour is demanding justice.

Pakistan's foreign ministry says that Peter Lavoy, head of Washington's South Asia desk at the National Security Council, and Richard Olson, U.S. Special Representative for Afghanistan and Pakistan, are meeting Friday with Pakistani civilian and military leaders in the first high-level exchange since the drone strike.

Pakistan considers the drone strike a violation of sovereignty, while the U.S. accuses Pakistan of providing safe havens for militants.

The family of Mohammed Azam, the taxi driver, is outraged that no one has publicly acknowledged that an innocent man died in the drone strike.
