Iran is threatening recreational and tourist sites worldwide and insisting it is still building missiles three weeks into an escalating war in the Middle East. The United States is deploying more warships and another 2,500 Marines to the region. As Israeli strikes landed in Tehran, Iran launched more attacks on Israel and energy sites in neighboring Gulf Arab states. With little information coming out of Iran, it was not clear how much damage its forces have suffered in the punishing U.S. and Israeli strikes that began Feb. 28 — or even who was truly in charge of the country. But Iran's attacks are still choking off oil supplies and denting the global economy.

Iran's new supreme leader released his first statement since succeeding his late father. Ayatollah Mojtaba Khamenei said Thursday that Iran would keep up its attacks on its Gulf Arab neighbors and use the effective closure of the strategic Strait of Hormuz as leverage against the United States and Israel. Khamenei, 56, who Israel suspects was wounded in the opening salvo of the war, did not appear on camera, as his statement was read by a state TV news anchor. The statement included a vow to avenge those killed in the war, including in a strike on a school that killed over 165 people.

Israeli ground troops for the first time have pushed into areas of a central Gaza city where several aid groups are based. An Israeli military official on Monday confirmed the incursion that appears to be the latest effort to carve up the Palestinian territory with military corridors. Deir al-Balah is the only Gaza city that has not seen major ground operations or suffered widespread devastation in 21 months of war. That has led to speculation that the Hamas militant group holds large numbers of hostages there. The main group representing hostages' families said it was "shocked and alarmed" by the incursion.

Syria's defense minister has announced a ceasefire just hours after government forces entered a key city in the volatile Sweida province. Tuesday's announcement follows deadly sectarian clashes between Druze factions and Sunni Bedouin tribes that killed over 30 people. That's according to Syria's Interior Ministry. However, fighting and allegations of civilian abuses by security forces continue. Meanwhile, Israel launched airstrikes on Syrian military convoys, claiming to protect the Druze minority near its border. Syria condemned the strikes, accusing Israel of aggression. The United Nations has urged all parties to stop the violence and engage in dialogue as ser escalation. Sectarian tensions remain high.

Israel has struck military tanks in southern Syria, where government forces and Bedouin tribes clash with Druze militias. Dozens of people have been killed in the fighting between local militias and clans in Syria's Sweida province. Government security forces that were sent to restore order on Monday also clashed with local armed groups. The Interior Ministry has said more than 30 people died and nearly 100 others have been injured in that fighting. U.N. Deputy Special Envoy for Syria Najat Rochdi has expressed "deep concern" over the violence in the country struggling for stability after a 13-year civil war.

The Israeli military says five soldiers have been killed in an attack in northern Gaza. Health officials in the Palestinian territory say Israeli strikes killed 51 people. The bloodshed came as Israeli Prime Minister Benjamin Netanyahu was visiting the White House on Tuesday for talks with President Donald Trump about a ceasefire plan. There was no announcement of a breakthrough from that meeting. But there were signs of progress toward a deal. The soldiers' deaths could add to pressure on Netanyahu to strike a deal in Israel where polls have shown widespread support for ending the 21-month war.
