Syrian Militants Attack Russian Base at Khmeimim

This is from this RT report. The rocket attack was launched from within the Idlib de-escalation zone, "... controlled by the Hayat Tahrir al-Sham terrorist group ..."

Khmeimim has been a frequent target of attempted attacks by terrorist groups, who used rockets and explosive-laden drones to target the base. None of the attacks have been successful, but the Russian military have sounded alarms over the jihadists being in possession of advanced technology, saying they may use them against less-protected targets in Syria and elsewhere.

In this interview Vanessa Beeley talks about UK FCO financing of the "White Helmets" which are a group with close ties to Hayat Tahrir al-Sham.
