Suspected attack by US forces kills many in northwest Pakistan

Wana: Foreign troops including US forces in Afghanistan killed at least 20 people including women and children in northwest Pakistan on Wednesday a provincial governor said.

The attack involving helicopters took place before dawn in the village of Angor Adda in the South Waziristan region.

"It is outrageous" Owais Ahmed Ghani governor of North West Frontier province said in a statement.

"This is a direct assault on the sovereignty of Pakistan and the people of Pakistan expect that the armed forces ... would rise to defend the sovereignty of the country and give a befitting reply" he said.

Pakistani Defence Minister Ahmed Mukhtar said aircraft belonging to foreign forces in Afghanistan attacked three houses at 4.30 a.m. (2230 GMT) but declined to comment further.

He added that the Foreign Ministry was investigating.

A spokesman for Afghanistan’s Nato-led force said she had no information about the incident while a spokesman for a the US-led coalition force declined to comment referring questions to the US Central Command.

Differing reports suggested ground troops were also involved in the attack.

"Troops came in helicopters and carried out action in three houses at around 3am (2100 GMT)" Gul Nawaz a shopkeeper in the village said.
