ISTANBUL (Reuters) - Syrian rebels dealt a blow to a U.N. envoy's proposal for a ceasefire in the northern city of Aleppo as his team headed there on Tuesday, saying the plan would only benefit the Syrian government at the expense of the opposition.
U.N. Syria envoy Staffan de Mistura has been trying to broker a truce in the city, which is at the forefront of clashes between pro-government forces and a range of insurgents, including Islamist brigades, al Qaeda's hardline Syria wing Nusra Front and Western-backed units.
