Lebanon`s Iran-backed Hezbollah movement said it fired a fresh barrage of rockets across the border on Wednesday after a strike blamed on Israel killed two civilians.
The group had already fired rockets at northern Israel late on Tuesday "in response" to the civilian deaths.
Hezbollah has exchanged near-daily fire with the Israeli army since its ally Hamas carried out an unprecedented attack on Israel on October 7, triggering war in Gaza.
It has stepped up its rocket fire on Israeli military bases in recent days.
Hezbollah fighters fired "dozens of Katyusha rockets" at a border village in northern Israel "as part of the response to the Israeli enemy`s attacks on... civilian homes," the group said in a statement.
On Tuesday, rescue teams said an Israeli strike on a house in the southern village of Hanin killed a woman in her fifties and a girl from the same family.
Since October 7, at least 380 people have been killed in Lebanon, mostly Hezbollah fighters but also 72 civilians, according to an AFP tally.
Israel says 11 soldiers and eight civilians have been killed on its side of the border.
