ISLAMABAD: A Pakistani man who says he lost his son and brother in an American missile attack in the country's northwest is demanding damages from the CIA.

Mirza Shahzad Akbar, a lawyer for Kareem Khan said on Monday that his client will file a lawsuit against the director of the CIA and the US defense secretary unless he receives $500 million in compensation.

The action is likely to draw attention to the issue of civilian casualties in drone strikes close to the Afghan border.

There have been more than 100 such attacks this year, more than twice the amount last year.

Washington does not publicly admit firing the missiles. US officials privately say little beyond that the attacks are killing al-Qaida and Taliban militants.
