A hospital supported by Doctors Without Borders (MSF) in Yemen has been hit by a rocket killing at least four people, the charity says.
The incident on Sunday in the northern governorate of Saada near the Saudi Arabian border also left another 10 people injured, the group said.
In a series of tweets, MSF said it was the third "serious incident" in as many months affecting its facilities in the country.
"We strongly condemn this and we reiterate to all parties to the conflict that patients & medical facilities must be respected," a statement by MSF on Twitter said about the incident in the town of Razeh.
The organisation did not say who was behind the attack, but that "planes were seen flying over the facility at the time".
Yemen is currently facing a humanitarian crisis brought on by the war between the Houthis and pro-government forces.
The conflict has killed almost 6,000 people so far according to the UN.
