YEREVAN, AUGUST 27, ARMENPRESS. Russian Foreign Minister Sergei Lavrov and U.S. Secretary of State John Kerry have rounded up the talks on Syria, which they have been holding in Geneva for more than 12 hours, “Armenpress” reports, citing TASS.

Coordination of Moscow and Washington's efforts in fighting with terrorists in Syria was the main issue on the agenda.

Talks with Russian Foreign Minister Sergei Lavrov that lasted more than 12 hours were dominated by discussions of the situation in Syria and Ukraine, U.S. Secretary of State John Kerry told a news briefing here upon their completion.

He said he was thankful to Lavrov for speding the whole day at the table of negotiations, adding that the talks had been long but constructive.

There can be no full-fledged ceasefire in Syria without separation of the opposition from terrorists, Lavrov said.

"I don't see any possibility of assuring a really durable, full-fledged ceasefire without the separation of healthy opposition forces from terrorists," he said. "The understanding of this task between us and our American partners gets increasingly clearer.".

UN Special Envoy on Syria Staffan de Mistura told a meeting in Geneva on Friday about his vision on resumption of the inter-Syrian talks, Russian Foreign Minister said.

"We met Staffan de Mistura. He has interesting ideas on how the United Nations should be used for the solution of humanitarian problems. He has plans to resume and in fact start a political dialogue," Lavrov stressed.

Russia is calling for an earliest possible convocation of a new round of pan-Syrian negotiations, Lavrov said.

"We believe this task is overripe and the convocation of a new round of negotiations between the (Syrian) government and the entire spectrum of opposition forces should be announced very shortly," he said.

Russia handed information on the groupings making up Jabhat al-Nousra terrorist organization to the U.S. on Friday, Lavrov said.

"We familiarized them (U.S. counterparts TASS) with the layout, with our vision of what smaller groupings constitute this organization," he said. "We hope our counterparts will scrutinize the information and it'll help them.".

Kurds should have full participation in the political process to solve the Syrian problem while remaining part of a united state, Sergey Lavrov.

"We, with our American colleagues, have confirmed the necessity of an urgent resumption, start of the political process involving all Syrian sides," Lavrov said.

"As for various aspects of Turkish presence on the Syrian territory, including the Kurdish factor which is so much written about these days, our U.S. counterparts and we confirmed the importance of an emergency resumption and start of a political process where all the Syrian parties should participate," Lavrov said.

"I'm convinced the Kurds should have a full-fledged representation in that process, should remain an integral part of the Syrian state and be part of a solution to the problem rather than a factor that someone will be using to split Syria, as the latter will trigger a chain reaction throughout the region while no one is interested in it," he said.
