Doctors Without Borders (MSF) on Thursday condemned Israel’s undercover arrest raid committed earlier that day at al-Ahli hospital in the occupied West Bank city of Hebron.

In a statement, the organization urged “the relevant military authorities to respect the special status that [International Humanitarian Law] grants to medical facilities and the wounded and sick.”

The organization said that Azzam Ezzat Shalaldah, 20, who was shot by an Israeli settler last month, was a patient of MSF and was being treated in their Mental Health Support Program “for victims of political violence.”

MSF said that the way in which Shalaldah was detained was “serious” and contrary “to the principles of neutrality and respect of the medical mission.

The International Humanitarian Law requires the respect of health facilities and forbids any intrusion of the armed forces in these structures,” adding that international law “demands that sick and wounded people would be treated without any discrimination in conformity with medical ethics.”

During the undercover raid, Shalaldah’s cousin, Abdullah Azzam Shalaldah, 28, was shot and killed while coming out of a bathroom in the hospital ward, unaware of the arrest raid taking place. His other cousin, Bilal, who was in the room with Shalaldah was handcuffed during the incident, but not detained.

MSF demanded that the relevant authorities inform and train “members of the armed forces on their obligation to respect medical facilities and personnel, as well as patients… and their caretakers” in order to prevent another incident of this kind.
