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. Its focus is on procuring explosives and producing drones that can be flown into Israeli positions, 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 group received from Tehran to aid displaced families in its Shi'ite heartlands, 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.
