US presses Pakistan on border fire

The United States on Thursday accused Pakistan of allowing insurgents to fire on US troops in Afghanistan as it renewed its call on the uneasy war partner to crack down on extremists.
US officials have reported a sharp rise in cross-border attacks against its forces, amid a deterioration of relations after US forces secretly raided Pakistan to kill the world's most wanted man, Osama bin Laden.
Lieutenant General Curtis Scaparrotti, the deputy US commander in Afghanistan, said that rocket and mortar fire against his forces appears to come from within sight of Pakistani military posts.
He said that the border forces come from Pakistan's Frontier Corps, who are locally recruited and not as highly trained as regular army units.
