The Israeli military said Wednesday its fighter jets had "begun a series of strikes in Lebanon," raising fears of a war between the two sides after months of cross-border fire and increasing tension fueled by the regime’s war on Gaza.

The regime said its warplanes struck several Hezbollah targets in response to rocket fire from Lebanon. 

Lebanese media said three villages were hit, CBS News reported. 

The strikes came hours after fire from Lebanon wounded multiple people in northern Israel, according to medics. 

Hezbollah chief Hassan Nasrallah said Tuesday that fire from southern Lebanon would end when the attack on Gaza stops and a cease-fire is established. 

"If they (Israel) broaden the confrontation, we will do the same," Nasrallah warned in a televised address.

Fears have been growing of another full-blown conflict between Israel and Hezbollah. The cross-border fire has already forced tens of thousands of people on both sides of the border to be evacuated.

Since Israel launched its onslaught in Gaza on October 7, at least 243 people have been killed in Lebanon, including civilians, according to an AFP tally.

On the Israeli side, nine soldiers and six civilians have been killed, according to Israeli official figures.
