When Israel bombed buildings outside the southern Lebanese city of Sidon, Mohamed Arkadan and his team rushed to an emergency unlike anything they had ever seen.

About a dozen apartments had collapsed onto the hillside they once overlooked, burying more than 100 people. Even after 17 years with the civil defense forces of one of the world's most war-torn nations, Arkadan was shocked at the destruction. By Monday afternoon — about 24 hours after the bombing — his team had pulled more than 40 bodies, including children's, from the rubble, along with 60 survivors.

Egypt’s top diplomat on Tuesday deplored Israel’s “serious escalation” in southern Lebanon, after the Israeli military said it launched a “limited and focused” ground incursion.

Foreign Minister Badr Abdelaty warned that Israel’s escalation threatens to inflame the entire region “in a way that will lead to dire security and humanitarian consequences,” according to a statement from the Egyptian Foreign Ministry.

The Israeli military said it launched a fresh strike on south Beirut on Tuesday.

"The IDF (Israeli military) conducted a precise strike in Beirut," the statement said, without offering details, while local media outlets reported simultaneous strikes on an apartment in a building in Jnah near al-Zahraa Hospital, and on another region in Beirut's southern suburbs.

"The United States has indications that Iran is preparing to imminently launch a ballistic missile attack against Israel," a senior White House official told AFP on Tuesday, speaking on condition of anonymity.

"We are actively supporting defensive preparations to defend Israel against this attack," the official said in a statement, warning that such an action "will carry severe consequences for Iran."

The Israeli army has been carrying out secretive ground operations to destroy Hezbollah infrastructure in Lebanese villages close to the border for the past year, military spokesman Rear Adm. Daniel Hagari said Tuesday.

He said that the current ground maneuvers in Lebanon are an expansion of the previous year’s operations.

Israel said its ground troops crossed into Lebanon overnight, launching what the military described as "localized" raids to root out Hezbollah fighters and infrastructure.

Hezbollah, meanwhile, said it saw no sign of Israeli forces and its troops were ready to confront them.

Spanish Foreign Minister José Manuel Albares has urged 1,000 Spanish civilians currently in Lebanon to leave the country and for Israel to stop its assault.

Albares said there are still commercial flights available to leave, but that he is in contact with Spain’s defense ministry to prepare a possible evacuation.

Hezbollah’s media office says an Israeli airstrike on Beirut’s southern suburb destroyed the building housing the offices of a religious TV station.

The media office said that there were no weapons stored in the building where Al-Sirat TV, a Shiite Muslim religious TV station, had its offices.

Israeli Defense Minister Yoav Gallant briefed U.S. Defense Secretary Lloyd Austin on ground operations the army launched inside south Lebanon targeting Hezbollah positions, his office said on Tuesday.

"The minister discussed the localized and targeted raids that the IDF (Israeli army) launched overnight, against Hezbollah terror targets in the border area of southern Lebanon," said the statement from the defense ministry.

Italian Premier Giorgia Meloni said Tuesday that “a de-escalation at regional level is urgent and necessary.”

“The protection of civilians remains the priority along with guaranteeing the security of the Italian military contingent of UNIFIL present in southern Lebanon," she said in a statement.
