US Defence Secretary Leon Panetta 'losing patience' with Pakistan

Washington is running out of patience with Pakistan over alleged safe havens for Taliban militants, US Defence Secretary Leon Panetta has warned.

On an unannounced trip to Kabul, he said Islamabad must act against the Haqqani militant network, which attacks Nato troops based in Afghanistan.

Mr Panetta's visit comes amid a recent rise in insurgent attacks in the war against the Taliban, including one on Wednesday in which 22 people died.

Pakistan denies providing safe havens.
