GENEVA (AFP) – The UN said Tuesday it had suspended all humanitarian aid convoys in Syria after a deadly air raid hit trucks delivering aid near Aleppo, killing a Red Crescent staff member and civilians.

As an “immediate security measure, other convoy movements in Syria have been suspended,” Jens Laerke, spokesman for the UN humanitarian agency told reporters in Geneva.

Red Cross spokesman Benoit Carpentier said the director of the Syrian Red Crescent’s sub-branch was among those killed in the attack.
