From CNN:ISLAMABAD, Pakistan (CNN) -- Hundreds of militants, believed to be foreign fighters, launched attacks on various military check posts in Pakistan's border with Afghanistan Saturday night and early Sunday morning, military officials said.
The ensuing fighting left 40 militants and six Pakistan soldiers dead, said military spokesman Gen. Athar Abbas.
"This is one of the largest attacks we have seen," Abbas said.
The attacks occurred at checkposts and military camps in the Mohmand agency, part of the lawless Federally Administered Tribal Areas where U.S. and Pakistani officials have reported a presence of militants.
Abbas said the fighters crossed into Pakistan from Afghanistan, and used rocket launchers and machine guns in their attacks. They have since been repelled, he said.
Pakistan and Afghanistan share a porous 1,500-mile border.
