Israel's military said it struck on Sunday rocket launchers in southern Lebanon which it said threatened civilians, ahead of the funeral in Beirut of slain Hezbollah chief Hassan Nasrallah.

"A short while ago, the IDF (military) conducted a precise intelligence-based strike on a military site containing rocket launchers and weapons in Lebanese territory, in which Hezbollah activity was identified," a military statement said.

"Additionally, several rocket launchers that posed an imminent threat to Israeli civilians were struck in southern Lebanon."

This is a developing story.
