The Israeli military said Tuesday it had killed a senior Hezbollah commander in a strike on Beirut, a day after the one-year anniversary of the October 7 attack was marked by mourning and demonstrations around the globe.

The military said the strike killed Suhail Husseini, who it said was responsible for overseeing logistics, budget and management of the militant group.

There was no immediate comment from Hezbollah.

The military said Husseini was involved in the transfer of advanced weapons from Iran and their distribution to different Hezbollah units, and that he was a member of the group's military council.

Israeli strikes have killed Hezbollah's overall leader, Hassan Nasrallah, and several of his top commanders in recent weeks. Last week, Israel launched what it says is a limited ground incursion into southern Lebanon.

Hezbollah says it has already replaced its slain commanders. It has vowed to keep firing rockets, missiles and drones into Israel until there is a cease-fire in the Gaza Strip, where its ally Hamas has been at war with Israel for a year

Meanwhile, Palestinian militants in Gaza fired a barrage of rockets into Israel on Monday, underscoring militants' resilience in the face of a devastating Israeli offensive in Gaza that has killed about 42,000 Palestinians, according to local medical officials, destroyed large areas and displaced around 90 per cent of its population.

A year ago, Hamas-led militants blew holes in Israel's security fence and stormed into army bases and farming communities, killing some 1,200 people, mostly civilians, and abducting another 250. They are still holding about 100 captives inside Gaza, a third of whom are believed to be dead.

Israel is now at war with Hamas in Gaza and its ally Hezbollah in Lebanon, which began firing rockets at Israel on October 8, 2023. On Monday, Lebanon's Health Ministry said an Israeli strike in the country's south, part of a wider bombardment, killed at least 10 firefighters.
