Official: Recent Taliban Violence Harms Hundreds of Afghan Civilians Ayaz Gul ISLAMABAD - Officials in Afghanistan alleged Saturday the Taliban has "killed or wounded" nearly 800 civilians since signing the February 29 peace-building deal with the United States. A spokesman for the Islamist insurgency swiftly rejected the charges. The allegations came on a day when Washington's peace envoy for the war-torn country, Zalmay Khalilzad, again called on the warring sides to work for peace, saying the U.S.-Taliban agreement "provides a historic opportunity for Afghanistan." A national security council spokesman in Kabul, while releasing details of the stepped-up insurgent violence, claimed the Taliban conducted more than 2,800 "terrorist activities" between Feb. 29 and April 20, killing and wounding "789 civilians during this period." Javid Faisal went on to say Afghan security forces in counter attacks also inflicted more than 2,700 casualties on the Taliban. "Last week was the bloodiest since the U.S.-Taliban deal, with the Taliban killing 34 and wounding 62 civilians across 17 provinces," he said without elaborating. Taliban spokesman Suhail Shaheen, when contacted by VOA for his reaction, questioned the veracity of the government claim on civilian casualties. "This is a general claim, can they say where and when?" Shaheen asked. Battlefield clashes have escalated in Afghanistan as the annual spring fighting season arrives, killing scores of combatants on both sides in the past week alone. Afghan media reported government forces suffered up to 100 deaths. .
