U.N. peacekeepers in Lebanon said they shot down an "aggressive" Israeli drone that appeared to target them, moments before a second drone attacked with a grenade.

In a statement Sunday, the United Nations peacekeeping force in Lebanon (UNIFIL) said that "an Israeli drone" had approached its troops "in an aggressive manner" on Sunday afternoon.

"The peacekeepers applied necessary defensive countermeasures to neutralize the drone," according to the force.

Later that afternoon, "an Israeli drone came close to a UNIFIL patrol operating near Kfar Kila and dropped a grenade," the statement continued.

"Moments later, an Israeli tank fired a shot toward the peacekeepers. Fortunately, no injury or damage was caused to the UNIFIL peacekeepers and assets," it added.
