Officials said the two missiles were fired from the suspected US drones at a house in Ladha area of South Waziristan. They feared that death toll could rise. Ladha is said to be the stronghold of chief of Tehrik-e-Taliban Pakistan Baitullah Mehsud. The area has been targeted for the first time by US drones. Pakistan has been protesting over a wave of missile strikes attributed to US-led forces in Afghanistan in recent months which killed more than 50 people. Pakistan's tribal regions of South and North Waziristan have been experiencing missile strikes in the past, which also killed several top Taliban and al-Qaeda fugitives.
