Doctors Without Borders is seeking security guarantees to continuing working in Yemen after a hospital it supports was bombed.

Mego Terzian, president of MSF France, said Thursday that he and the group's board "won't be ready to send at any price our personnel in countries where there is huge danger."

Speaking to reporters in Paris after Monday's bombing in the northern province of Saada, he said, "We need to have minimum guarantees that our humanitarian space is secure."

One nurse was injured by the airstrikes apparently targeting rebels in Yemen. MSF says it shares the hospital's GPS coordinates regularly with the Saudi-led coalition and its roof was clearly identified with its logo.

MSF operates in eight Yemeni governorates, while many foreign aid groups and even U.N. personnel have been evacuated.
