A Syrian army rocket attack on a rebel-held district in the city of Aleppo killed at least 20 people and left another 25 missing, opposition activists said on Tuesday.
"The rocket brought down three adjacent buildings in Jabal Badro district. The bodies are being dug up gradually. Some, including children, have died in hospitals," Mohammad Nour said by phone from Aleppo.
He said testimony from survivors indicated that another 25 people were still under the rubble.
