Syria's "conflict has not ended yet," even after the departure of former president Bashar al-Assad, the UN's envoy to the country warned Tuesday, highlighting clashes between Turkish-backed and Kurdish groups in the north.
"There have been significant hostilities in the last two weeks, before a ceasefire was brokered... A five-day ceasefire has now expired and I am seriously concerned about reports of military escalation," said Geir Pedersen, the UN's special envoy for Syria.
"Such an escalation could be catastrophic."
