Pakistan on Sunday buried 24 troops killed in a Nato cross-border air raid that has pushed a crisis in relations with the United States towards rupture.  Nato helicopters and fighter jets attacked two Pakistan military outposts on Saturday, killing the soldiers in what Pakistan said was an unprovoked assault.

Islamabad retaliated by closing the border crossings used by the international coalition to supply its troops in neighboring Afghanistan. Nato and US officials expressed regret about the deaths of the Pakistani soldiers, but the exact circumstances of the attack were unclear. – Text by Reuters, photos by Agencies.
