Suspected U.S. missiles struck a training facility allegedly operated by Pakistani Taliban leader Baitullah Mehsud and a militant hide-out Friday, killing 15 people and wounding 27 others, intelligence officials said, according to AP. The two attacks by drone aircraft took place in South Waziristan, a Mehsud stronghold close to the Afghan border, two officials said on condition of anonymity because they were not authorized to speak to the media. They were the latest in more than 40 such strikes by the United States against militant targets in the border area since last August. Washington does not directly acknowledge being responsible for the attacks, which kill civilians as well as militants. The strikes came as the Pakistani military prepares for its own offensive in South Waziristan to eliminate Mehsud, who has been blamed for a string of deadly suicide attacks across the country that have killed more than 100 people in the past month. One attack targeted an abandoned seminary in the village of Mantoi that was allegedly being used by militants from Mehsud's group for training, said the officials. The other struck a hide-out in the nearby village of Kokat Khel, they said. In total, 15 people were killed and 27 others were wounded, they said.
