"In the course of 24 hours in the city of Aleppo terrorists fired from multiple rocket launchers," the statement says, adding that several districts of the city, as well as a shopping mall and southern farms were shelled.
Syria has been mired in civil war since 2011, with government forces loyal to President Bashar Assad fighting a number of opposition factions and extremist groups. On February 27, a US-Russia brokered ceasefire came into force in Syria. Terrorist groups such as Islamic State (ISIL, also known as Daesh), as well as Jabhat Fatah al Sham (also known as Jabhat al-Nusra, or al-Nusra Front) are not part of the deal. Both groups are banned in a range of other countries.
The Syrian city of Aleppo has seen intense fighting over the past few months, with the Syrian army and local militia forces having managed to encircle large groups of terrorists in some districts of the city.
