ISLAMABAD , Pakistan -LRB- CNN -RRB- -- 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 . A Pakistan soldier on patrol last fall against militants on the border of the Mohmand agency district . 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 . In recent months , Afghan officials have blamed militants operating from havens in the lawless tribal regions of Pakistan of sneaking into their country and attacking security personnel . Pakistan has repeatedly denied involvement and bristled at the accusation , saying that Afghan lawmakers were making allegations without proof . Abbas ' Sunday comments reverse those allegations , with Pakistan now blaming militants from Afghanistan attacking inside its soil .
