The Pakistani President, Pervez Musharraf, has told a United States Congressional delegation visiting Islamabad that his country will not tolerate any militant attacks across the border into Afghanistan.
General Musharraf told the delegation, led by the Republican senator, John McCain, that Islamabad was doing all it could to stop any attacks, citing the arrest of hundreds of Taleban fighters.
His comments came after a spate of attacks in Afghanistan which have left at least 90 people dead during the past two weeks.
Afghan officials say Taleban fighters are launching attacks from the safety of Pakistan's lawless border regions.
