The aid group Doctors Without Borders says a projectile from an unknown source has hit a hospital it supports in Yemen's northern Saada province, killing four and injuring 10. The group, known as MSF, says in a statement that the Sunday attack led to "the collapse of several buildings of the medical facility." Of those injured, three are MSF staff, and two are in critical condition, it said. MSF operates in eight Yemeni provinces at a time when many foreign aid groups and even United Nations personnel have been evacuated. "This is the third severe incident in the last 3 months. Our teams struggle on a daily basis to ensure the respect of health facilities," MSF wrote said, per Reuters.
Shiite rebels known as Houthis took over the capital, Sanaa, in September 2014; in March, a Saudi-led coalition started launching airstrikes against Houthi and allied forces' positions. Saada, a Houthi stronghold, has faced a particularly intense bombardment. "There is no way that anyone with the capacity to carry out an air strike or launch a rocket would not have known that the Shiara Hospital was a functioning health facility providing critical services and supported by MSF," says a rep. MSF keeps warring factions updated with GPS coordinates of its locations, the group notes. (Read more Yemen stories.)
