Three United Nations observers and a translator have been wounded by shelling in Rmeish, southern Lebanon, the UN peacekeeping mission said.
In a statement, UN Mission,UNIFIL says the shell exploded near the group who were on a foot patrol along the UN-demarcated Blue Line that divides southern Lebanon from Israel.
Lebanon’s state news agency reported that an Israeli drone strike was behind the explosion, but the Israeli military denied it was responsible.
The mission said those hurt were receiving treatment and that it was investigating the blast’s origin.
It described the targeting of peacekeepers as “unacceptable”.
No details have been given about the nationality of the observers or their condition. The Lebanese translator is reported to be stable.
In recent days, tensions have again picked up along the unofficial border between Israel and Lebanon, with casualties on both sides.
