MOSCOW, May 29. /TASS/. Russian and U.S. top diplomats, Sergei Lavrov and John Kerry, had a telephone conversation on Sunday to discuss the situation in Syria and Russia’s initiatives on joint operation against terrorist organizations and other armed groups that violate the ceasefire in Syria, the Russian foreign ministry said.
"Sergei Lavrov once again stressed the necessity of the soonest closure of Syria’s border with Turkey from where infiltration of militants continue and of Washington’s keeping its promise to dissociate Syrian opposition groups it has contacts with from Jabha al-Nusra terrorists who are not covered by the ceasefire," the ministry said.
The sides agreed to invigorate work with all of the Syrian parties and with all the countries concerned to have them obey by the resolutions of the International Syria Support Group and United Nations Security Council resolutions 2254 and 2268, the ministry said, adding that the two ministers discussed other topical international issues, including the situation in UKraine, and certain issues of the bilateral agenda.
A ceasefire regime brokered by Russia and the United States on February 22 officially came into effect in Syria at midnight Damascus time on February 27. This does not cover terrorist groups such as Islamic State and Jabhat al-Nusra, both outlawed in Russia, and other groups recognized as terrorist by the United Nations Security Council.
An hour before the ceasefire came into force, the United Nations Security Council adopted a resolution in support cessation of hostilities in Syria. The document was initiated by Russia and the United States and won support from all the 15 members of the United Nations Security Council.
