The Russian Foreign Ministry said that Russian and Turkish military experts died in Idlib in the past two weeks.
"In mid-January, the Russian and Turkish militaries made another effort to introduce a ceasefire in the Idlib de-escalation zone. However, instead of reducing their military activities, terrorists increased attacks," TASS cited the statement as saying.
"Russian and Turkish military experts have died tragically. Drone attacks on Russia’s Hmeymim Air Base are ongoing," the ministry noted.
