Hezbollah targets Israeli troops on Lebanese border

Hezbollah targeted Israeli soldiers near the Lebanese border village of Labbouneh with artillery shells and rockets on Wednesday, the group said in a statement, a day after Israel said it had killed two successors to Hezbollah's slain leader.

Sirens sounded in northern Israel on Wednesday, the Israeli military said, adding three Israeli military personnel were severely injured on Tuesday and Wednesday during combat in southern Lebanon.

The Lebanese Health Ministry announced 36 people were killed and 150 others were wounded in Israeli attacks across Lebanon on Monday.

Israeli Prime Minister Benjamin Netanyahu said on Tuesday Israeli airstrikes had killed two successors to Hezbollah's slain leader.

Netanyahu spoke in a video released by his office hours after the deputy leader of Hezbollah, which is reeling after a spate of killings of senior commanders in Israeli airstrikes, left the door open to a negotiated ceasefire.

"We've degraded Hezbollah's capabilities. We took out thousands of terrorists, including (Hassan) Nasrallah himself and Nasrallah's replacement, and the replacement of the replacement," Netanyahu said, without naming the latter two.

Israeli Defence Minister Yoav Gallant said Hashem Safieddine, the man expected to succeed Nasrallah, had probably been "eliminated". It was not immediately clear whom Netanyahu meant by the "replacement of the replacement".

Later, Israeli military spokesman Daniel Hagari said Israel knew Safieddine was in Hezbollah's intelligence headquarters when fighter jets bombed it last week and Safieddine's status was "being checked and when we know, we will inform the public."

Safieddine has not been heard from publicly since that airstrike, part of an escalating Israeli offensive after a year of border clashes with Hezbollah. The group is the most formidably armed of Iran's proxy forces across the Middle East and has been acting in support of Palestinian militants fighting Israel in Gaza.

"Today, Hezbollah is weaker than it has been for many, many years," Netanyahu said.

Israel's military said on Tuesday that heavy air strikes against underground Hezbollah installations in southern Lebanon over the prior 24 hours killed at least 50 fighters including six sector commanders and regional officials.

The Israeli military said it had sent the 146th Division into south Lebanon, the first reserve division to have been deployed over the border, and was extending ground operations against Hezbollah from southeast Lebanon into its southwest.

A military spokesperson declined to say how many troops were in Lebanon at one time. But the military had previously announced that three other army divisions were operating there, meaning that thousands of soldiers were likely on Lebanese soil.

Overnight, Israel again bombed Beirut's southern suburbs where Hezbollah is headquartered and said it had killed a figure responsible for budgeting and logistics, Suhail Hussein Husseini - the latest in a string of assassinations of some of Hezbollah's top officials.

An Israeli military spokesperson said over 3,000 rockets had been fired into Israel from Lebanon so far in October, but interceptions by air defences had prevented many casualties and significant damage.

The mushrooming Israeli-Hezbollah conflict has killed well over 1,000 people in Lebanon in the past two weeks and prompted the mass flight of more than a million.
