SAN JUAN, Puerto Rico — Doctors Without Borders said Monday that four of its vehicles came under fire while they evacuated staff from a hospital in Haiti’s capital as gang violence in the city surges.

The aid group said the incident forced it to suspend services at the Turgeau Emergency Center on Saturday. It noted one of its convoys “was repeatedly and intentionally fired upon, despite prior coordination with authorities.”

No one was killed, but staff members received minor injuries, said Benoit Vasseur, the group’s head of mission in Haiti.

Doctors Without Borders said it is the second time in less than four months that it has been forced to suspend operations at that health facility in Port-au-Prince.

The Turgeau Emergency Center was one of the few remaining hospitals in Haiti’s capital that was fully functional as gangs that control 85% of Port-au-Prince step up attacks in a bid to control more territory. More than 5,600 people were killed across Haiti last year, according to the United Nations.
