Moscow: A top Russian diplomat on Thursday said that the regime of President Bashar Al Assad is losing "more and more" control of Syria and a victory by the opposition cannot be ruled out.

"As for preparing for victory by the opposition, this, of course, cannot be excluded," Deputy Foreign Minister Mikhail Bogdanov was quoted as saying by the ITAR-TASS news agency.

"You need to look the facts in the eyes - the government regime is losing more and more control over a large part of the country's territory."
