UNIFIL forces announced on Sunday that their forces were exposed to gunfire, likely by non-state armed groups, in three separate incidents while they were patrolling around their positions in Yater, Derkiva and Qalawiya. UNIFIL continued: The shooting occurred in Yater at a close distance of five meters from the peacekeeping forces. She indicated that the source of the shooting in the other two incidents was about 100 meters and 200 meters away, respectively. Two patrols returned fire in self-defense, and after a short exchange of fire, the patrols resumed their planned activities. No peacekeepers were injured. She said that the presence of weapons outside the control of the state within UNIFIL's area of operations constitutes a violation of UN Security Council Resolution 1701. It is unacceptable to target peacekeeping forces carrying out tasks assigned to them by the Security Council. UNIFIL reminded all parties of their duties under international law to ensure the safety and security of United Nations personnel at all times, and to take all necessary measures to prevent harm to civilians. She concluded: Any attack on UNIFIL peacekeeping forces constitutes a serious violation of international humanitarian law and Resolution 1701, and may amount to a war crime.
