ICRC member killed in Yemeni airstrike SANAA, Yemen, June 21 (UPI) -- The International Committee of the Red Cross said circumstances surrounding the killing of one of its staff members in Yemen was unclear. The ICRC said it was "deeply shocked" by the death of staff member Hussein Saleh, 35, in the southern Yemeni province of Abyan. "Saleh and three other staff members were assessing the humanitarian situation in the region, which has been severely affected by the recent fighting," the organization said in a statement. The circumstances behind this incident remain unclear. Dibeh Fakhr, an ICRC representative working in the Yemeni capital, told the BBC that Saleh was died of injuries received in an airstrike on the region. The southern province has been the site of heaving fighting between pro-government forces, supported by the U.S. military, and al-Qaida sympathizers. Yemeni violence attributed to al-Qaida has escalated since longtime President Ali Abdullah Saleh resigned in February following a year of political unrest. Fakhr said it was unclear if the airstrike that killed his colleague came from an unmanned drone of from Yemeni forces.
