PESHAWAR: American unmanned planes fired two missiles at a house in a Pakistani tribal region close to the Afghan border Thursday, killing seven alleged militants, the latest in a barrage of such attacks, intelligence officials said. The strike in North Waziristan was the third attack there in the past 24 hours. Thursday's strike in the Datta Khel area killed five unidentified foreign and two local militants, intelligence officials said. They did not give their names in line with the policy of the agency they work for. Two other attacks Wednesday killed seven suspected militants. There have now been at least 20 suspected US missile strikes in Pakistan this month, many of them in North Waziristan. There were 21 such attacks in September, nearly double the previous monthly record. Many of the missile strikes are reported to hit at militants focused on fighting in Afghanistan and using North Waziristan as a safe haven.
