DUBAI (Sputnik) – Earlier in the day, the International Syria Support Group said in a statement that all parties to the Syrian conflict should adhere to the provisions stipulated in the deal on cessation of hostilities.
"The opposition used the right to defend itself after numerous violations of the ceasefire by the government forces," he said.
"We demand an end to constant shelling, especially of civilians, and urge to adhere to the truce," the spokesman added.
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 as Daesh and Nusra Front.
A US-Russia-brokered ceasefire came into force across Syria on February 27. Daesh and Nusra Front, both outlawed in Russia, were not part of the deal.
