The UN has suspended peace talks aimed at ending Syria’s five-year civil war, the organisation’s special envoy has said.
Staffan de Mistura called the temporary halt, saying there had been a lack of progress in the first week.
It comes as the Syrian government claimed to have broken a siege of two towns north-west of Aleppo.
The advance, reported on Syrian state television, severs a key rebel supply route into the city.
On the talks, Mr de Mistura admitted “there’s more work to be done”. They are due to resume later this month.
“It is not the end and it is not the failure of the talks,” he said.
“Why? They came and they stayed. Both sides insisted on the fact that they are interested in having a political process started.”
