"The ball is now in the United States' court and the next step will be American pressure on Turkeyand Saudi Arabia to stop funding terrorists and stop the flow of weapons," Shaaban said.
"It is very possible to close the borders and keep out mercenaries," she added.

Syrian forces have recently been making back-to-back advanceswith the support of the Russian airstrikes.
Earlier, Syrian troops backed by Russian airstrikes made major gains to the west of the central city of Daesh-held city of Palmyra.
"The (Syrian) army is able not only to preserve the gains it has made, but also to confront new areas in order to liberate the largest possible number of villages," Shaaban added.
Syria has been gripped by foreign-backed militancy since March 2011. According to a February report by the Syrian Center for Policy Research, the conflict has claimed the lives of over 470,000 people, injured 1.9 million others, and displaced nearly half of the countrys pre-war population of about 23 million within or beyond its borders.
