Hezbollah has launched dozens of rockets at the occupied Golan Heights after Israeli aircraft struck deep inside Lebanon, as fears of an all-out war grow.

The Israeli military said it hit Hezbollah weapons storage facilities in the Bekaa Valley overnight with the Lebanese health ministry confirming that one person was killed and 30 others injured in the attack.

In response, Hezbollah, which is backed by Iran, said it targeted Israeli military positions in the Golan with a rocket barrage.

Israeli authorities say two homes were hit and one person was injured in the counter-offensive strike

Meanwhile, the Palestinian Fatah movement is accusing Israel of assassinating a senior member of its armed wing in Lebanon in an effort to ignite a regional conflict.

The Israeli military said it had killed Khalil al-Makdah in a strike in the southern port city of Sidon because he was operating on behalf of Iran’s Revolutionary Guards and was involved in directing attacks in and smuggling weapons to the occupied West Bank.

It was reportedly the first strike on a Fatah member since the start of the Gaza war, which has led to escalating cross-border hostilities between Israel and Hezbollah.
