Tensions between Kabul and Islamabad flared up Wednesday after Pakistani PM Gillani phoned Afghan President Karzai to express “serious concerns” over cross-border attacks and demand a quick end to such raids. The move comes as hundreds of Afghan militants launched fresh attacks on Wednesday in the Upper Dir area along the Pak-Afghan border. Meanwhile, Afghan officials said at least 78 people were killed on their side of the border on the same day in clashes between security forces and the Taliban in the province of Nuristan. Provincial Governor Jamaludin Badar said that the attackers came from Chitral in Pakistan. Both governments have been blaming one another for not containing the militants. Kabul also accuses Islamabad of launching rockets into its territory.
