Israel is preparing for a potential response from Hezbollah following the killing of its leader, Hassan Nasrallah, in an Israeli airstrike. The IDF has issued restrictions on gatherings in central Israel, limiting them to 1,000 people. Flights to and from Israel are facing delays and cancellations due to security concerns. In northern Israel, gatherings are limited to 10 people in the open and 150 inside. Despite recent Israeli attacks on Hezbollah, the group has not yet launched a significant assault on Israel, but defense officials warn that they still pose a threat.
