Olson said it is the internal matter of Pakistan whether to take military action against the Taliban or to hold peace talks with them. "This is up to the government of Pakistan, and the United States will support it," the U.S. ambassador said in a televised interview on Pakistan Television News.

He said the U.S. wishes Pakistan success in coping with the challenges related to its internal security.

"We are not anti-peace process," he said and added that the U.S. does have an interest in the foreign groups that threaten it.

Olson extended condolence to the families who had been victim of the terrorist acts of Taliban and termed it 'regrettable'.
