DERA ISMAIL KHAN, Pakistan A U.S. drone strike killed at least seven people on Monday in a tribal region along Pakistan's western border, local officials said, the first such attack in a month as a diplomatic feud strains U.S.-Pakistani ties.
At least four missiles were fired from the unmanned aircraft at a suspected militant training center in Azam Warsak, just west of Wana, the main town in the South Waziristan tribal agency, intelligence officials in South Waziristan said.
"According to initial reports there were foreigners among the dead," one of the officials said.
A second official said the foreign nationals killed included three people from Turkmenistan and two Arab nationals.
It is the first time since January 23 that intelligence officials have reported a U.S. drone attack, marking a resumption of a campaign that has become the centerpiece of U.S. efforts to halt militants launching attacks on its soldiers in Afghanistan.
Many analysts believe Washington halted the attacks for weeks to avoid further inflaming anti-American fury in Pakistan just as it pressures Islamabad to release Raymond Davis, a U.S.consulate employee imprisoned after shooting two Pakistanis last month in what he said was an attempted robbery.
Others speculate the pause was due to poor weather or an inability to find reliable targets as militants hunt down Pakistanis they believe are feeding intelligence information.
Washington, which provides Pakistan with billions of dollars a year in military and civilian aid, is leaning hard on the government of President Asif Ali Zardari to release Davis on grounds the U.S. national is shielded by diplomatic immunity.
RISK, NECESSITY FOR PAKISTAN
Yet neither can the government afford to unleash popular fury in a case that has galvanized anti-American sentiment in Pakistan. Protesters have burned U.S. flags and demanded the Davis be tried for murder in local courts.
Davis, whose precise connection to the U.S. government has not been specified, is locked in a jail in the city of Lahore after a hearing on his immunity was delayed until March 14.
Talat Masood, a retired Pakistani general and military analyst, said the United States may have resumed the raids in a recognition that the case may drag out for some time.
The drone strikes, which are not publicly acknowledged by either country, are another delicate situation for the vulnerable Zardari government, battling an insurgency of its own and struggling to hold together a fragile coalition.
The attacks are seen as a risk and a necessity for Pakistan, under pressure from its chief ally in the West to do against militants but also facing mounting resentment from Pakistanis who decry the government for bowing to U.S. wishes.
There is also growing debate over the effectiveness of the strikes, which have killed al Qaeda and Taliban figures but have been unable to reach senior militants living in cities like Quetta and Karachi that Pakistan has made off-limits to strikes.
According to a new report in the Washington Post, only two of the drone attacks in Pakistan last year killed militants who were senior enough to appear on a U.S. most-wanted list.
Citing data from government and independent sources, the Post said that despite an escalation in the attacks the number of high-ranking militants killed was modest and may have slipped.
