"The Russian military commanders reassured that they are ready to provide to any rebel group, which is ready to sign the truce agreement, any support and help they may need whether it is food or medical supplies," Ahmad said.
Ahmad said that the Russian military command had given party leaders, clerics and civil activists the green light to contact any rebel group in Syria on its behalf.
"We will not ask them to disarm, we will ask them to test a ceasefire deal and offer them on Russia's behalf all necessary support they may need," the politician said, adding he hoped more groups would sign the truce in the coming weeks.
On February 22, Russia and the United States brokered an agreement on a ceasefire in Syria. The ceasefire came into force on February 27, with the ceasefire generally holding across the country despite reported minor violations.
