MOSCOW (Sputnik) — On Saturday, media reported of the killing of the group of volunteers in Idlib's town of Sarmin. The United States has already condemned the move.
"I am appalled by the targeted and heinous murders of heroic White Helmets volunteers who put their own safety at risk to save lives on all sides of the Syrian conflict," Johnson said, as quoted by the UK governmental press service.
The UK official stated that the death of the organization's volunteers was "a huge loss for their families, Syria and the world."
In March, Syrian President Bashar Assad said that the group was affiliated with the al-Qaeda terrorist organization, outlawed in many countries including Russia.
