Iran fires missiles at Israel for first time since ceasefire

Iran launched missiles at Israel on Sunday in retaliation for an Israeli strike in Beirut earlier in the day, marking the first direct Iranian missile attack since the April 8 ceasefire.

Why it matters: This marks a major regional escalation and threatens to unravel U.S.–Iran negotiations and reignite the war.

Driving the news: Israel Defense Forces said sirens sounded in northern Israel as four missiles were launched from Iran, but that air defense systems were operating to intercept the threat.

• Iranian state media reported a third wave of missiles had been launched, but Israeli officials said all had so far been intercepted.
• President Trump told Axios he would call Israeli Prime Minister Benjamin Netanyahu and urge him not to retaliate for Iran's missile attack.

Zoom in: Israel Defense Forces spokesperson Brig. Gen. Efi Defrin said in a statement Tehran had "made a grave mistake," adding that the IDF was working on military plans and will continue striking Hezbollah targets in Beirut.

• Iran's Islamic Revolutionary Guard Corps said the missiles were launched as a warning to Israel, and it threatened broader attacks across the region if Israeli strikes in Lebanon continued.
• One of the targets was Ramat David Air Base in northern Israel, the IRGC said.

What they're saying: Iran's military said Israel had "crossed all red lines" in intensifying its attacks in southern Lebanon and targeting the south Beirut suburb of Dahieh.

• "If it expands its attacks in that area, or responds to Iran's action, it will face more forceful blows, and devastating attacks will be launched" against Israel and its supporters, the military added.

What we're watching: An IDF spokesperson said following the Israeli military strike in Beirut and after a situational assessment, the IDF was preparing for incoming fire at Israel in the coming hours.
