Live updates: Israel extends assault on Tehran, Beirut; Iran threatens revenge after U.S. sinks warship

Israeli forces bombarded Iran and Lebanon on Thursday, as the assault entered a sixth day and the wider region grappled with conflicts emerging on multiple fronts. Iranian Foreign Minister Abbas Araghchi said the United States would “bitterly regret” its strike on an Iranian frigate in the Indian Ocean. Hezbollah and Israel escalated attacks against each other and were fighting on the ground inside southern Lebanon. Azerbaijan, Saudi Arabia and the United Arab Emirates reported fresh attacks, as Iran said it launched a wave of retaliatory strikes throughout the region, including against Kurdish forces in Iraq. Iran denied firing a missile toward Turkey, a day after Turkey said NATO air defenses shot down an Iranian ballistic missile heading toward its airspace. Targeting Turkey, a NATO member, would mark a major escalation in the conflict.
