MOSCOW, May 30. /TASS/. Moscow is concerned over Washington’s threats to use force against Syria’s military, Russian Foreign Minister Sergey Lavrov said on Tuesday.

"As you know, there have been not only threats [of using force by the US against Syria’s army], but a fact of using force in this area [Al-Tanaf on the border between Syria and Iraq]," Lavrov said.

"I believe this situation is rather alarming as it directly affects Syria’s sovereignty. Certainly, these issues need to be solved, and our troops are doing this now," the Russian top diplomat has noted.

"I believe this situation is rather alarming as it directly affects Syria’s sovereignty. Certainly, these issues need to be solved, and our troops are doing this now," Russia’s top diplomat said.

The effort is underway now through a channel set up to prevent unintentional incidents between Russia’s Aerospace Forces and the US-led coalition, Lavrov said.

"But of course, the effort would be much more efficient if in addition to the channel, which has a rather limited agenda, the US agreed to join the work on coordinating parameters of de-escalation zones," the Russian diplomat stressed.
