"This issue is not being practically considered at this time," Gatilov told RIA Novosti.
Gatilov added that a priority matter is the creation of an agreed list of terrorist groups and a representative opposition group to launch political dialogue with the Syrian government to resolve the four-year Syrian civil war.
Syria has been mired in civil war since 2011, with forces loyal to Syrian President Bashar Assad fighting against numerous opposition factions and extremist groups.
International talks on the settlement of the Syrian crisis started in October. Earlier this month, the UN Security Council adopted a resolution on Syrian settlement, which reaffirmed the goals to bring the entire spectrum of the political groups in the country to the negotiating table and said the next round of the talks would take place in January 2016.
According to the deputy foreign minister, the UN Security Council' s resolution also outlined the need for a mechanism to check a ceasefire observation by all parties to the conflict, once it is established.
