Russian President Vladimir Putin has offered a new unilateral humanitarian pause for Syria's war-ravaged Aleppo, urging rebels to use it to leave the city's eastern, besieged districts. <br/><br/>Russian Defense Ministry said, Mr Putin ordered his forces to open humanitarian corridors to eastern Aleppo tomorrow, along with two routes in order to prevent a senseless loss of life. <br/><br/>The Ministry said, rebels inside Aleppo had taken heavy losses during fighting and were effectively trapped and they have no chance to break out of the city. However, rebel groups dismissed Russia's latest offer and said they will not give up the city and would not surrender.
