(The NewYork Times): Rockets launched at a U.S. military base and a joint U.S.-Afghan airfield in southern Afghanistan in recent weeks are believed to have been fired by the Taliban, according to three American military officials, in what would amount to a clear breach of the peace agreement between the United States and the insurgent group. Roughly a dozen rockets struck in late July around Camp Bastion, a sprawling air base used by Afghan and American forces in the southern province of Helmand. And several rockets were fired within the last week or so at Camp Dwyer, a large U.S. military base about 50 miles south of Bastion. A Taliban commander familiar with the region denied that the group had carried out any strikes on American bases in Helmand and said that the group would investigate. The rocket strikes may also have been carried out by a Taliban faction that is against the agreement, according to one military official who was briefed on the matter. There were no U.S. casualties in either attack, nor a public response from Washington during a stretch in which American officials have struggled to keep an already shaky peace process on track.
