Doctors Without Borders (MSF) said Sunday there had been 77 attacks on medical facilities it supports in Syria and Yemen over last year.
The figure was released as the medical charity marked one-year since its trauma centre in the northern Afghan province of Kunduz was bombed by a US jet, killing 42 people. A US report later said that the clinic was mistaken for a Taliban position.
Since the Kunduz strike on October 3, 2015, hundreds of thousands of people in north-eastern Afghanistan have been left without access to life-saving surgical care, MSF said.
Meinie Nicolai, president of MSF Belgium, said at a press conference in Kabul that the charity wants to reopen the Kunduz clinic, but there is still no timetable.
MSF repeated its call for the UN Security Council to implement a resolution it passed in May that called for the protection of hospitals in war-zones such as Afghanistan, Syria and Yemen.
