At least two barrel bombs have hit the largest hospital in the rebel-held area of Aleppo in Syria.
It makes it the third airstrike on hospitals this week in the city – which is surrounded by Syrian government forces.
Around 250-thousand people are thought to be trapped in Aleppo.
It comes after the UN announced an inquiry into the recent bombing of an aid convoy in Syria. 20 people were killed and 100 tonnes of supplies were destroyed in the attack.
