Nato troops fire at insurgents in Pakistan

Kabul: Nato says its troops have fired 20 artillery rounds at insurgents inside Pakistan after coordinating with the South Asian nation.

The military alliance says it fired the rounds after insurgents attacked its troops in Afghanistan's eastern Paktika province with rockets from across the border.

Pakistani officials could not immediately be reached for comment.

Pakistani has condemned the unilateral missile strikes conducted by US forces as a violation of its sovereignty.
