Intensified shelling of Israel by the Lebanese movement "Hezbollah" could cause a serious escalation, said the Israeli military, quoted by Reuters and BTA.
"The increasing aggression of "Hezbollah" is pushing us to the brink of what could become a wider escalation that could have devastating consequences for Lebanon and the entire region," Israeli military spokesman Rear Admiral Daniel Hagari said in an English-language video address.
Last week, the Iranian-backed "Hezbollah" launched its largest-ever barrage of rockets and drones in the eight-month conflict in Gaza, during which the group traded blows with Israeli forces alongside the war in the Palestinian enclave.
The US and France are working to settle hostilities along Lebanon's southern border through negotiations. "Hezbollah" says it will not cease fire until Israel stops its military offensive in Gaza.
"Israel will take the necessary measures to protect its peaceful citizens - until security is restored along our border with Lebanon," Hagari said.
