UN Envoy to Syria calls on US and Russia to save talks

The UN envoy to Syria Staffan de Mistura has urged the US and Russia to urgently intervene "at the highest level" to salvage Syrian talks. 
Speaking after briefing the UN Security Council on the faltering peace process, de Mistura said that a truce agreed in February was "barely alive", according to the (BBC). 
Violence in Syria has intensified in recent days, despite the ceasefire. 
Calling on the US and Russia to cooperate, de Mistura said that the legacies of both President Barack Obama and President Vladimir Putin were linked to the success of the peace process in Syria. 
De Mistura said that the fragile "cessation of hostilities" established in February had been "saved from total collapse" but "could collapse any time". 
In order for the peace talks to succeed, de Mistura said, hostilities would need to be again reduced to the levels seen immediately following the February truce agreement. 
His press briefing followed the third session of talks this year between the major actors in the conflict. 
There will be one or two more rounds of talks before July, de Mistura said. He said that the latest round had been "overshadowed by a substantial and worrisome deterioration of hostilities."
