The United Nations has come under fire for sharing the coordinates of hospitals in rebel-held areas of Syria with Russia, only for one of them to be bombed days later.

The organisation gave the GPS locations supplied by NGOs operating in Idlib and Eastern Ghouta to Russia and the US as part of a new “notification system”.

One of the hospitals whose details were shared with the UN on March 12 - in the Arbin neighbourhood of besieged Ghouta - was targeted in a direct strike on March 20.

At least one patient was reported to have been killed by what medics suspected to be a “bunker-buster” bomb. It was not immediately clear whether it was a Syrian or Russian attack, however Moscow is known to use the more precise bombs, which burrow deep underground before exploding.
