Israel said its troops are now active in southern Lebanon in what the Israel Defense Forces called "limited, localized, and targeted ground raids" targeting Hezbollah positions.
Israel believes it has eliminated around 30 top Hezbollah leaders over the last several weeks, including Hezbollah leader Hassan Nasrallah, who was killed in an Israeli airstrike in Beirut, U.S. and Israeli officials said.
US Embassy in Jerusalem issues 'shelter in place' order
The U.S. Embassy in Jerusalem issued a statement directing all government employees and their family members "to shelter in place until further notice," following reports of an imminent Iranian missile attack on Israel.
The embassy noted the "continued need for caution and increased personal security awareness as security incidents, including mortar and rocket fire and unmanned aircraft system," which it said "often take place without warning."
"The security environment remains complex and can change quickly depending on the political situation and recent events," it added.

Netanyahu warns Israelis of 'testing days ahead'
Prime Minister Benjamin Netanyahu urged unity among Israelis in a video statement published Tuesday, as Israel Defense Forces operations in Lebanon expanded and amid fears of an imminent Iranian missile attack.
"We are in the midst of a campaign against Iran's 'Axis of Evil,'" the prime minister said. "These are days of great achievements and great challenges."

The "great achievements," Netanyahu said, included the assassination of Hezbollah leader Hassan Nasrallah in a Beirut airstrike last week, plus the defeat of an alleged Hezbollah plan to launch an infiltration attack into northern Israel.
The country still faces "big challenges," he continued.
"What I ask of you is two things: One -- to strictly obey the directives of the front-line command, it saves lives. And second -- to stand together. We will stand firm together in the testing days ahead."
"Together we will stand, together we will fight and together we will win."

Iran to launch ballistic missiles at Israel 'imminently,' US official says
A senior White House official told ABC News on Tuesday that the U.S. "has indications that Iran is preparing to imminently launch a ballistic missile attack against Israel."
"We are actively supporting defensive preparations to defend Israel against this attack," the official added.
"A direct military attack from Iran against Israel will carry severe consequences for Iran."
Israel Defense Forces spokesperson Rear Adm. Daniel Hagari told reporters, "At this moment we don't identify an aerial threat from Iran."
"The U.S. informed us that Iran is preparing to fire directly on Israel," he said, asking the public to be "responsible and vigilant and I will be here to update you."
A senior Israeli official told ABC News, "If Iran attacks Israel the reaction will be severe."

Israeli special ops teams active in Lebanon for almost a year, IDF says
Israel special operations teams have been operating in southern Lebanon since November, an Israeli security source said Tuesday, conducting around 70 missions in groups of 20 to 40 operators.

The troops spent around 200 nights inside Lebanon, making it the most intense series of special operations missions in Israel's history, the official said.
The units operated between 1 and 2 miles inside Lebanese territory, the official said, blowing up and dismantling hundreds of Hezbollah facilities including tunnels.
Some tunnels doubled as weapons caches and others stretched to the Israeli border. Officials said on Tuesday they believed Hezbollah was planning an imminent "Oct.7-style invasion" of northern Israel.
The security source claimed that Hezbollah's elite Radwan Force was at times as little as six hours from launching such an attack.

ABC News was not immediately able to independently verify the official's claims.
The Israeli special operations units operating in southern Lebanon encountered almost no resistance, the official said, and did not suffer any casualties.
Though some 2,000 Radwan troops are believed to be present within 3 miles of Israel's border -- and between 6,000 and 8,000 in southern Lebanon in total -- they have not been fighting.
"During these operations, the troops also collected valuable intelligence and methodically dismantled the weapons and compounds, including underground infrastructure and advanced weaponry of Iranian origin," the Israel Defense Forces said in a statement.
"Some of the weapons were recovered and taken by the soldiers back into Israeli territory."
