"The United Nations envoy for Syria has said he is “appalled and shocked” by indiscriminate rocket warfare targeting civilians in Aleppo after three days of a fresh rebel offensive in which dozens have died." "Syrian insurgents on Sunday kept up their shelling of government-controlled areas of the city, killing at least seven people, including three children, state TV reported, and used car bombs and tanks to push into new territory in western areas. The Syrian government claimed the opposition fighters used toxic gas."
