Syria's Foreign Minister Walid al-Moallem says a U.S.-Russia-brokered cease-fire agreement is still viable and says his administration is prepared to take part in a unity government.

In an interview broadcast on the Mayadeen TV channel Monday, al-Moallem accused the U.S., Britain, and France of convening a U.N. Security Council meeting a day earlier in order to support "terrorists" inside Syria. But he said ongoing communications between U.S. Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov meant a truce agreement brokered two weeks ago is "not dead."

Syria's military declared the cease-fire ended one week ago.

Al-Moallem reaffirmed his government's proposed roadmap to end Syria's war, saying Damascus would support a referendum on a new constitution followed by parliamentary elections and the formation of a unity government.
