Two Russian medics have been killed in a militant shelling of a Russian field military hospital in the Syrian city of Aleppo, with Moscow blaming the US, UK and France for the attack.

Russia’s Defense Ministry said on Monday that the two female Russian medics were killed in the shelling of the health facility in the government-held part of the Syrian city while two doctors were also severely injured in the attack.

The first female medic was killed on the spot when a shell hit the reception area of the hospital, while the second died from her wounds later, Russia’s Defense Ministry spokesman Major General Igor Konashenkov said.

Konashenkov added that the United States, Britain and France were to blame for the attack as they sponsor terrorist groups in Syria.

“No doubt, the opposition’s gunmen carried out the shelling (but) the instigators are also to blame, those who created and armed these beasts in human form and called them ‘opposition’ in order to unburden themselves,” said Konashenkov.

“The sponsors of terrorists in the US, UK and France, as well as other countries sympathizing with them, you are to blame,” he said.

The Russian official accused the three Western countries of tipping off the militants about the hospital’s location, saying it was quite clear for Moscow "where the militants got the precise data and coordinates” of the Russian hospital at the moment when it started working.

Russian Foreign Minister Sergei Lavrov said Saturday that Moscow would hold talks with Washington this week on a timeframe for the withdrawal of all militants from Aleppo.

However, Takfiri terrorist groups rejected the offer on Monday, saying they would not accept the withdrawal plan.
