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, because Israel will likely respond to the Iranian attack. The latest: Iranian state media reported a third wave of missiles had been launched, with Iran's Islamic Revolutionary Guard Corps saying one of the targets was the Ramat David Airbase in northern Israel.The IRGC said these were launched as a warning to Israel, and it threatened broader attacks across the region if Israeli strikes in Lebanon continued.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.Israeli officials said all missiles had so far been intercepted.President Trump has been briefed on the situation, a U.S. official 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.State of play: 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."The IDF has reinforced its defensive capabilities and is maintaining a high level of readiness and alertness for a variety of defensive and offensive scenarios," the spokesperson said.Senior military officials were conducting assessments and closely monitoring developments, the spokesperson said, urging the public to remain vigilant.Editor's note: This is a breaking news story.
