More violence kills nine in Aleppo
Syrian rebels and government forces have shelled each other's neighbourhoods in Aleppo, leaving at least nine dead and scores wounded on both sides.
The violence erupted as the diplomatic focus moved to Moscow where the UN envoy for Syria was to hold talks in efforts to restore a piecemeal ceasefire that would also include the contested northern city.
Aleppo, Syria's largest city, has been the centre of violence in recent weeks but was not part of the latest partial truce.
Syrian state TV said shells hit a government-held area during morning rush hour, killing seven people and wounding at least 35, while activists reported two dead in a rebel neighbourhood.
The activist Britain-based Syrian Observatory for Human Rights confirmed the shelling of government-held parts of the city, and also said that seven were killed, including a child. The observatory said more than 50 were wounded, including some who were in critical condition, which could raise the death toll.
The observatory and another activist group, the Local Coordination Committees, said government forces also shelled rebel-held parts of the city on Tuesday, killing two and wounding several.
The observatory said more than 250 civilians have been killed in 12 days of violence in both government- and rebel-held parts of the city.
Also in northern Syria, war planes carried out intense air strikes on the city of Raqqa, the de facto capital of the extremist Islamic State group, in the early hours of Tuesday. Activist groups said it was not clear if the war planes were Russian or those of the US-led coalition.
The observatory, which has a network of activists around the country, said there were more than 35 air raids and that 18 people were killed including five members of the Islamic State group. It said dozens were wounded.
The anti-IS group Raqqa Is Being Slaughtered Silently said the air strikes killed 10 and wounded dozens. The group said there were calls from mosque loudspeakers for the residents to donate blood.
IS suffered major setbacks over the past months in Syria against government forces and US-backed Kurdish fighters including the loss of the central historic city of Palmyra.
