"Following an unsuccessful nighttime attack, the districts were shelled with multiple launch rocket system and mortar fire. The militants carried out shelling from the Kastello shopping center and the Muhaim Handrat locality. The shelling was indiscriminate, with both government forces positions as well as civilian areas being hit. Over 15 people were killed and dozens have been injured," the center's spokesperson said.
Syria has been mired in civil war since 2011, with government forces loyal to Syrian President Bashar Assad fighting numerous opposition factions and extremist groups, such a the Nusra Front and the Islamic State. Both groups are outlawed in many countries, including Russia.
