At least 11 people have been killed in a U.S. drone missile attack in South Waziristan, intelligence officials said on Friday. The missiles struck a house around Friday noon in a village near Mizai Narai, a bordering area with Afghanistan, the officials said. U.S. drone aircraft fired many missiles at a house owned by a tribesman, killing at least 11 people and injuring three others, news reports say. Identities of deceased were not known immediately. However, residents of the area said those killed were not militants and were from a local family.
