The top U.S. commander on the NATO force in Afghanistan has met with Pakistan's army chief to discuss security issues.

The Pakistani military announced Saturday that General John Allen flew to Rawalpindi Saturday and met with General Ashfaz Parvez Kayani.

In a statement, the military said the meeting was meant to discuss operations in border areas and coordination to avoid what it called “untoward incidents.”

Pakistan closed U.S. and NATO supply routes to Afghanistan after a cross-border NATO air attack in November that killed 24 Pakistani soldiers at a checkpoint.

Saturday's meeting could help ease U.S.-Pakistani tensions ahead of a NATO summit on Afghanistan in Chicago later this month.
