Four rescue workers have been injured in an Israeli bombing in southern Lebanon that hit two ambulances, according to the association that owned the vehicles and state media, AFP reports.

Lebanon’s National News Agency said the latest Israeli strike targeted two ambulances belonging to the Risala Scout Association, which operates rescue teams and is affiliated with the Shia Amal movement, a Hezbollah ally.

The association said, “A drone from the Israeli occupation forces deliberately targeted… the two vehicles, causing moderate injuries to four paramedics.”

It said the attack took place at dawn when the two ambulances were called to evacuate the wounded in the village of Tayr Harfa, some three kilometers (two miles) from the Israeli border.

The Israeli army said it had used a drone to target a “terrorist cell that attempted to fire from Lebanon toward the area of Rosh Hanikra in northern Israel”.

It said troops had observed “two suspicious vehicles” that arrived in the area, but said “the strike was directed at the terrorist cell and not at the vehicles.”
