MIR ALI, Pakistan — Suspected U.S. missiles struck a militant compound in northwestern Pakistan today, killing at least three people in an area teeming with Taliban and al-Qaida fighters who often launch attacks against NATO troops in Afghanistan, said Pakistani officials.

It was the second strike in as many days in North Waziristan, a mountainous area along the Afghan border where unmanned aircraft operated by the CIA have launched dozens of attacks. The U.S. has urged the Pakistani military to target the area, but has faced resistance.

The compound struck by two U.S. missiles today was located in the village of Tabbi Tolkhel, a little over a mile northeast of Miran Shah, the main town in North Waziristan, said Noor Ahmed, the deputy political leader in the area.

There were conflicting reports about how many people were killed in the attack.

Ahmed said that tribesmen have recovered five bodies from the rubble. He did not know their identities.

Two Pakistani intelligence officials said three militants were killed and five others were wounded. They spoke on condition of anonymity because they were not authorized to talk to the media.

The Pakistani military has resisted launching an offensive in North Waziristan, saying its forces are stretched thin from other operations along the Afghan border. Many analysts suspect its resistance is also driven by its desire to preserve historic ties with Taliban militants in the area who could be useful allies in Afghanistan after foreign troops withdraw.

Given Pakistan’s reluctance, the U.S. has relied on missile strikes to target militants in Pakistan’s tribal areas but refuses to publicly acknowledge the existence of the covert program.

Pakistan publicly protests the strikes as violations of its sovereignty, but is believed to have assisted in at least some of the attacks.

On Saturday, a suspected U.S. missile strike flattened a house near North Waziristan’s town of Mir Ali, killing two alleged militants, according to intelligence officials.
