Local media in Iran said Monday that a "hostile drone" was shot down over the capital Tehran during the new round of fighting with Israel.

"A hostile drone belonging to the American-Zionist enemy was targeted and destroyed by air defenses in the skies over Tehran," the Mehr news agency reported, without elaborating.

The Israeli military said Monday it had struck and dismantled Iranian defense systems deployed across several areas in the country.

"Recently, defense systems were deployed in numerous areas across Iran as part of the regime's efforts to restore its detection and defense capabilities, which were degraded during Operation Roaring Lion," the military said.

Iran said Monday that the United States held responsibility for the resumption of fighting with Israel, saying Israel's actions "cannot be separated" from U.S. policy.

"Without a doubt, as I said, the actions of the Zionist regime in the region cannot be separated from U.S. policies," foreign ministry spokesman Esmaeil Baqaei said at a press conference in Tehran attended by AFP.

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.

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.
