Hezbollah said it targeted northern Israel's Dafna area with Katyusha rockets "in response to the Israeli enemy's attacks that targeted civilians in the town of Adloun, injuring several of them".

This comes after the Israeli military said its air force "struck two Hezbollah weapons storage facilities in southern Lebanon, containing rockets and additional weaponry".

Late on Saturday, Lebanon's state-run National News Agency said "the Israeli enemy launched a raid" on the town of Adloun, about 30 kilometers (19 miles) from the border with Israel, later saying the target was "an ammunition depot".

"Six civilians sustained moderate injuries," the NNA said on Sunday, revising the figure up from three the night before.

Rockets were still exploding about an hour after the strike was first reported, the NNA said, with videos circulating online showing several large explosions in Adloun.

"Shrapnel from the explosions flew to surrounding villages," the NNA said.

Hezbollah on Sunday said in separate statements that three of its fighters were killed.
