Moscow, Aug 3 (IANS/RIA Novosti): The resignation of UN and Arab League envoy to Syria Kofi Annan "opens the gates" for those backing a military intervention into the country to force out the ruling authorities, a Russian minister has said.

Annan, who assumed his post in February and authored a six-point peace plan aimed at ending the Syrian conflict, announced Thursday that he would quit by the end of the month, citing the deadlock at the UN Security Council over ways to resolve the current political crisis in the country.

"Annan's decision against extending his mandate as the UN envoy to Syria raises loads of questions regarding the future of this country. He is an honest international mediator but someone wants to push him out of the game to open the gates for forceful actions. This is obvious," Russia's Deputy Foreign Minister Gennady Gatilov wrote in his Twitter account Friday.

Since March 2011, the Syrian conflict has claimed 14,000-20,000 lives, according to estimates by Syrian opposition groups.
