Syria army tells last rebels to quit Aleppo

Syria's army on Tuesday urged the last remaining rebels and civilians to leave the besieged opposition enclave in Aleppo as it prepares to take full control of the devastated city. The evacuation of Aleppo's rebel sector is seen as a pivotal moment in the nearly six-year war that has killed more than 310,000 people and triggered a major humanitarian and refugee crisis. The government and other parties on the ground have agreed to allow 20 observers to be sent to east Aleppo to monitor evacuations, said UN spokesman Stephane Dujarric.
