MIRANSHAH, Pakistan - The deadly U.S. drone campaign in Pakistan's tribal zone resumed with a missile strike that killed four militants, two months after a NATO raid that killed 24 Pakistani soldiers.
The CIA campaign had reportedly been suspended to avoid worsening relations between the United States and Pakistan after the deadly Nov. 26 incident, which eroded even more the thin veneer of trust between the wary allies.
The four militants were killed late Jan. 10 when two missiles struck their compound on the outskirts of Miranshah in North Waziristan, a lawless tribal region near the Afghan border, security officials said.
The attack set the building on fire, and flames could be seen from the roofs of houses in Miranshah, which lies three miles away, residents reported.
It was the first missile strike in Pakistan since Nov. 17. It remains to be seen if it presages a new round of attacks on Taliban and al-Qaida-linked militants based in the remote territory bordering Afghanistan.
November's strike by NATO helicopters triggered outrage in Pakistan and aggravated tensions in an already shaky relationship with Washington. The incident prompted Islamabad to block alliance supply convoys heading to Afghanistan.
Islamabad also ordered the U.S. to last month leave Shamsi air base in western Pakistan, from where it is believed to have launched some of its drones. Others are thought to be fired from within Afghanistan.
A joint U.S.-NATO investigation concluded last month that a catalogue of errors and botched communications led to the soldiers' deaths. But Pakistan rejected the findings, insisting the strikes had been deliberate.
NATO's probe said that both sides failed to give the other information about their operational plans or the location of troops and that there was inadequate coordination by U.S. and Pakistani officers.
The U.S. drone campaign has reportedly killed dozens of al-Qaida operatives and hundreds of low-ranking fighters in Pakistan since the first Predator strike in 2004.
But the program has incensed many Pakistanis and fuels widespread anti-American sentiment throughout the country.
The Los Angeles Times reported last month that the U.S. Central Intelligence Agency had suspended drone strikes on gatherings of low-ranking militants in Pakistan due to the tensions caused by the campaign.
The latest drone strike came on the same day that a remote-controlled bomb killed 35 people and wounded more than 60 others in the troubled Khyber tribal region of northwest Pakistan.
The region had served as the main supply route for NATO forces operating in Afghanistan before the suspension triggered by the November incident.
There was no immediate claim of responsibility for the bombing but local residents suggested it was a tribal dispute.
The U.S. denounced the blast, which struck in a marketplace.
"By callously targeting innocent peoples, the extremists who planned and perpetrated this attack are just showing their contempt for the value of human life," State Department spokeswoman Victoria Nuland said.
"We remain deeply committed to working with Pakistan to address these kinds of terrorist threats and the results of violent extremism," she said.
Nuland added that Washington could not confirm reports that al-Qaida was behind the attack.
The border crossing for supplies to foreign troops fighting in Afghanistan remains closed. NATO said this month that it wants to get relations with Pakistan back on track "as quickly as possible" so it can be reopened.
