Pakistani tribesmen, bolstered by waves of volunteers, have killed dozens more foreign militants allegedly linked to al-Qaida near the Afghan border, officials said Wednesday. The latest deaths push the toll from more than two weeks of fighting in the South Waziristan region to more than 250, officials have said, leading the government to claim a victory against terrorism. Armed tribesmen turned on foreign militants and their local allies in the region, where Taliban and al-Qaida fighters have long found sanctuary, on March 19, apparently after a long-standing feud turned violent. According to three security officials on Wednesday, about 50 of those killed in the past 24 hours in South Waziristan were Uzbeks. About 10 local tribesmen and one Pakistani soldier also died, they said. Poor security in the region, where the government has minimal control, puts it largely off-limits to reporters, making it hard to verify what little information emerges.
