Doctors Without Borders says three of its staff were killed in an overnight bombing of a hospital in the embattled Afghan city of Kunduz.
NATO said a US air strike “may have” hit the hospital, which is run by the medical charity, adding that the attack may have resulted in collateral damage.
The MSF hospital is seen as a key medical lifeline in the region, which has been running “beyond capacity” in recent days of fighting which saw the Taliban seize control of the provincial capital for several days.
A statement by the MSF said, “At 2:10 am (20:40 GMT) local time… the MSF trauma centre in Kunduz was hit several times during sustained bombing and was very badly damaged."
