ISTANBUL — A Syrian rebel assault on government-held parts of Aleppo killed as many as 19 people, activists and Syrian state media said Tuesday, in attacks that included a deadly rocket strike on a hospital even as diplomats struggled to find ways to quell the fighting.
The United Nations special envoy for Syria, Staffan de Mistura, traveled to Moscow to push for a halt to the violence that monitoring groups say has killed more than 250 people in the past week. Russia is a key ally of Syrian President Bashar al-Assad.
