UN outraged over aid convoy attack in Syria

United Nations, Sep 20: The United Nations special envoy to Syria has voiced anger over the airstrike that hit an aid convoy of UN in the Syrian province of Aleppo.

UN special envoy to Syria, Staffan de Mistura said: "Our outrage at this attack is enormous ... the convoy was the outcome of a long process of permission and preparations to assist isolated civilians," Press TV reported.

On Monday, UN spokesman Stephane Dujarric said that at least 18 of 31 trucks in the convoy were hit while parked outside a Syrian Arab Red Crescent center in the province's Urm al-Kubra region.

"We understand a convoy has been hit. We are trying to get more information."

The Syrian Observatory for Human Rights claims the attack was carried out by Syrian or Russian jets, and that 12 Red Crescent drivers were killed in the attack.
