A British doctor who has worked in 20 different war zones says he has never before had to deal with the type of bombs being dropped on the Syrian city of Aleppo.
He's teaching Syrian doctors how to treat the terrible wounds caused by barrel and cluster bombs.
In the east of the city, only six hospitals remain.
But this month, hospitals have also been hit in Idlib and Damascus, while deliveries of supplies to hospitals in Douma have been blocked by Syria troops.
Accurate figures on the number of attacks are hard to come by, but there have been at least 382 attacks on hospitals since the start of the conflict, killing 757 medical personnel.
These are thought to be conservative figures, but they highlight the dangers of life as a Syrian doctor.
