Syria’s main opposition bloc has given warning that attacks by government forces in Aleppo province could stand in the way of the peace talks under way in Geneva.

The warning was sounded by the Higher Negotiations Committee (HNC), which sent a 17-strong opposition team, including three rebel leaders, to the Swiss city for talks.

Salim al-Muslet, HNC spokesman, said the opposition was waiting for reaction to the developments in Aleppo and other provinces.

'It is important for us to see the lifting of sieges of children starving to death,' she said.

'Since last night, big massacres have taken place in Syria and nobody is doing or saying anything.

'We do not know if the international community is completely blind or they do not want to do anything. We are here to know if they are keen to do anything - then we are waiting for them.'
