MIR ALI, Pakistan — Suspected U.S. missiles killed four people today in an al-Qaida and Taliban stronghold in northwest Pakistan, intelligence officials said, amid signs of greater cooperation between Islamabad and Washington.

The three missiles hit a compound and a vehicle in Dargah Mandi area of North Waziristan tribal region.

The identities of the dead were not immediately clear, said intelligence officials, who spoke on condition of anonymity because they were not authorized to speak to media. However, the area hit was a stronghold of the Haqqani network, an Afghan Taliban faction that is considered a major threat to U.S. troops across the border in Afghanistan.

Authorities recently confirmed another missile strike had killed Mohammad Haqqani, a son of the network's aging leader, Jalaluddin Haqqani.

The strikes have been one of several blows in recent weeks to militants on Pakistani soil. At least three Afghan Taliban commanders have been captured in recent weeks in Pakistan, including the No. 2 leader of the insurgents, Mullah Abdul Ghani Baradar.

Those arrests were the result of intelligence breakthroughs, U.S. Gen. David Petraeus, who oversees the war in Afghanistan, told reporters in Islamabad on Tuesday night. There also are unconfirmed reports of another Taliban leader, Mullah Kabir, being arrested.

Over the past 18 months, Pakistan has undertaken several army offensives in the northwest against Islamist militants. Those operations have mostly targeted militants attacking the Pakistani state, not militants fighting U.S. and NATO troops in Afghanistan.
