US drones fired at least 12 missiles, destroying a militant training camp and killing 14 Islamists on Tuesday in Pakistan's tribal region bordering Afghanistan, officials said.

The camp in Lowara Mandi, 50 km west of Miranshah, in North Waziristan district, was run by Taliban-linked Afghan warlord Hafiz Gul Bahadur, whose group has over 2,000 trained fighters, the officials said.
