An air strike hit a hospital in southern Syria that was supported by Doctors Without Borders (MSF), killing three people and wounding six others, including a nurse, the medical charity said on Tuesday.

"The strike on Tafas field hospital, some 12 kilometres (seven miles) from the Jordanian border, took place on the night of February 5. It caused partial damage to the hospital building, and put its heavily-used ambulance service out of action," MSF said in a statement.
