Hezbollah has remained committed to attacking Israel and has used a lull in hostilities since June to rearm, with a focus on procuring explosives and drones that can be used to attack IDF troops.
Lebanese terrorist group Hezbollah has spent three months preparing for a possible resumption of hostilities with Israel, after receiving an infusion of cash from Iran, according to Lebanese security personnel briefed on its activities.
The group, founded by Iran's Islamic Revolutionary Guard Corps (IRGC) in 1982, has been dealt severe blows in two wars with Israel since 2024, with thousands of fighters and many of its leaders killed, and much of its arsenal destroyed.
As part of efforts to combat Hezbollah, IDF troops now occupy a security zone in southern Lebanon, and political pressure has built up in Beirut for its disarmament.
It nevertheless remains committed to attacking Israel and has used a lull in hostilities since June to rearm, with a focus on procuring explosives and producing drones that can be flown into the security zone, two Lebanese security sources told Reuters.
One of the sources, and another close to Hezbollah, said the group had received tens of millions of dollars from Iran to help boost its military capabilities. That is in addition to around $200 million that the terror group previously received from Tehran, which Reuters reported earlier this month.
The group has been restoring command-and-control structures that broke down in key battles, according to one of those sources and three other security officials familiar with the group's operations.
In response to questions from Reuters, Hezbollah's media office rejected the suggestion that its command-and-control systems had been broken down.
Israel's military declined to comment. Iran's permanent mission to the United Nations in Geneva did not immediately respond to Reuters questions.
A US State Department spokesman said Washington would keep strangling Hezbollah's finances through sanctions and other measures. A US Treasury spokesperson said Iran was running out of money and ways to move money.
Hezbollah on alert for potential of renewed fighting
Hezbollah's effort comes amid continued tensions in the wider Middle Eastern conflict ignited by the US-Israeli war with Iran that began in February.
Hezbollah attacked Israel in support of Iran on March 2, triggering an Israeli response that led to a large number of individuals, mostly members of Hezbollah's Shi'ite Muslim constituency, being evacuated from areas in southern Lebanon.
Hostilities largely abated over the summer as an interim Iran-US deal included a Lebanon ceasefire and Washington-mediated talks between Lebanon and Israel. Full-scale hostilities have not resumed in Lebanon despite the collapse of the US-Iranian deal, though Israel continues strikes on Hezbollah terrorists in the south.
Hezbollah is on alert for a possible US-Iran escalation, potentially reigniting the Lebanon front.
The sources told Reuters the terror group had not yet managed to fully prepare its stockpiles or fighting force.
Hezbollah is still restocking, acknowledging this month that explosives seized by Lebanese authorities belonged to it and were intended for use against Israel. A Hezbollah official and a Lebanese security source told Reuters they were specifically for its explosive drones.
Hezbollah struggled to fight IDF
The terror group will also need to repair command-and-control capabilities after losses on key fronts, including the flashpoint town of Bint Jbeil and the strategic Ali al-Taher ridge, according to one of the Lebanese sources and three security officials.
They said Hezbollah's tactic of operating in small units and rationing the use of anti-tank rockets left some units isolated on those fronts, struggling to confront Israel's remotely operated systems, including weaponized drones and armed remote-controlled vehicles.
The Israeli military told Reuters it uses remotely-operated systems to monitor southern Lebanon and reduce troops' threat exposure.
Hezbollah has not explicitly said whether it would take part in the eruption of fresh hostilities, but its media office said it was wary of giving Israeli leaders any justification to escalate anti-Hezbollah efforts.
