Israel is girding for widely anticipated retaliatory attacks by Iran and Hezbollah, telling its people this week to stock up on food and water in fortified safe rooms, while hospitals prepare to move patients to underground wards and search-and-rescue teams position themselves in major cities.
The Israeli government’s security cabinet convened on Thursday night as speculation continued over how the country’s enemies might respond to the killing of a Hezbollah leader in Lebanon, and of Hamas’s top official while he was visiting Iran. Diplomats across the Middle East and elsewhere have tried to tamp down the tensions amid fears that the Israel-Hamas war raging in the Gaza Strip could broaden into a much bigger conflict across the region.
Intelligence has been sparse and changes frequently. But two Israeli officials and a senior Western intelligence official said that based on the latest information, Hezbollah, the Lebanese armed group closely allied with Iran, will likely strike first in a separate attack before Iran conducts its own retaliation. They spoke on the condition of anonymity because they were not authorized to speak publicly, and did not provide further details about the potential attacks.
The latest crisis follows the assassinations last week of Fuad Shukr, a top Hezbollah military commander, and Ismail Haniyeh, Hamas’s political leader. Israel has said it killed Mr. Shukr in retaliation for a rocket attack from Lebanon that killed 12 children and teenagers, while refusing to comment on the blast that killed Mr. Haniyeh in Tehran, which has been widely attributed to Israel.

Iran has vowed revenge for the killing of Mr. Haniyeh on its soil, calling it an egregious violation of Iranian sovereignty. Hassan Nasrallah, Hezbollah’s leader, said in an address this week that the group’s response to the killing of Mr. Shukr would be severe.
“Let the enemy, and those who stand behind them, await our inevitable response,” said Mr. Nasrallah. “We are looking for a true response, not a superficial one,” he added.
