An Afghanistan hospital of the international medical aid group Doctors Without Borders was raided by government troops who fired weapons in the air, threatened and assaulted several staff members, the group said on Friday.

The group condemned the “violent intrusion,” in which troops raided the facility on Wednesday and arrested three patients who were being treated there, calling it a breach of the Geneva Conventions.

Following the attack, Doctors Without Borders said that they temporarily suspended work at the Kunduz facility in the country’s northeast.

“This serious event puts at risk the lives of thousands of people who rely on the center for urgent care,” Dr. Bart Janssens, the organization’s director of operations, said in a statement. “We are shocked by this incident.”

However, Colonel Nader, the local army brigade commander, said he did not believe the army was behind the incident. “Afghan National Army Special Forces have neither raided any hospital nor arrested anyone whatsoever,” he said, according to the New York Times. “We completely deny that Afghan National Army had any involvement at all.”
