Two US soldiers missing in Afghanistan: NATO     STAFF WRITER 10:12 HRS IST Kabul, Jul 25 (AFP) A road and air search was underway today for two American soldiers who went missing in eastern Afghanistan, with local radio stations offering a reward for their safe return. The missing soldiers left their compound late Friday "and did not return", a statement from NATO's International Security Assistance Force (ISAF) said, amid reports one of them may already be dead. Their vehicle had been recovered in Logar province, south of Kabul, an official said yesterday. "Nobody has been found but there are reports that there may be a casualty and that the body has been removed from the scene," a military official said, speaking on condition of anonymity. All reports were unsubstantiated, he added. ISAF said a road and air search had been launched.
