According to the WHO, they were arrested on Wednesday while taking part in the mission. The organization has expressed concern over their fate and called for their immediate release. The arrests have raised further alarm about the deteriorating conditions in the besieged Palestinian territory. The hospital chief and health workers were carrying out their duties and should not be targeted in any way.
