UN Syria envoy presses for speedy Aleppo aid delivery

The United Nations Special Envoy for Syria called for all warring sides to agree by Sunday on a green light for a first safe delivery of relief supplies to the divided city of Aleppo. 
 
Staffan de Mistura said in a statement on Saturday that for logistical and operational reasons the first convoy must go via 
the Castello Road during a 48-hour humanitarian pause, although he was aware of rebel opposition to using that government-controlled route.
 
"The Special Envoy calls for all concerned to exert every effort so that, by this Sunday, 28 August 2016, we know where we stand," de Mistura said.
