Yemen’s Iran-backed Houthi rebels claimed an attack on Israel and said Israel-affiliated vessels would again be a target in the Red Sea, putting the Red Sea, the Gulf of Aden and the narrow Bab el-Mandeb Strait connected them in danger.

The statement from Brig. Gen. Yahya Saree was broadcast on the Houthis’ al-Masirah satellite news channel. During the Israel-Hamas war in the Gaza Strip, the Houthis killed at least nine mariners and sunk four ships in over 100 attacks, often targeting vessels with tangential or no ties at all to Israel.

Israel and Iran traded fire on Monday, seriously testing a fragile truce and threatening hopes for a deal to end the Middle East war.

The new attacks, including a strike on an Iranian petrochemical complex, came hours after U.S. President Donald Trump called on Israel to refrain from retaliating against Tehran's missiles.

U.S. President Donald Trump said Sunday he will call Israeli Prime Minister Benjamin Netanyahu to urge him not to retaliate against Iranian missile strikes on Israel, U.S. news outlet Axios reported.

"I am going to call Bibi right now and tell him not to retaliate," Trump was quoted as saying by Axios journalist Barak Ravid in a phone interview, using the Israeli leader's nickname.

Air raid sirens sounded in Israel on Sunday as its military worked to intercept barrages of incoming Iranian missiles for the first time since an April ceasefire took hold in the Middle East war.

The Israeli army reported the attack just hours after Tehran had threatened to retaliate for a new Israeli strike on Beirut's southern suburbs.

Iran threatened to retaliate against the United States and Israel for fresh strikes in Beirut's southern suburbs on Sunday, further dampening hopes for a lasting peace as the Middle East war reached its 100th day.

At least one person was killed and five others wounded in multiple shooting attacks in Israel on Sunday, authorities said, with one of the perpetrators killed.

The United States said it shot down a pair of Iranian drones threatening the Strait of Hormuz, the latest escalation of violence as the war crept into its 100th day on Sunday with no end in sight.

Iran still has "21, 22 percent" of its missiles left, U.S. President Donald Trump said, in a week in which Tehran fired dozens of them toward regional neighbors, despite a sputtering ceasefire.

The release of frozen Iranian funds has become a key issue in negotiations between Tehran and Washington aimed at ending their war, a senior Iranian official said.

Iran fired missiles at U.S. allies Bahrain and Kuwait on Saturday, after renewed American strikes against it, drawing a furious response from the Gulf monarchies and further undermining a fragile truce.
