The Bahrain Defence Force said in a post to social media on Wednesday that its air defenses intercepted an unspecified number of Iranian missiles and drones. Iran, the BDF said, "is continuing its systematic hostility."

Kuwait's Defense Ministry said in a statement posted to X on Wednesday that its defenses also intercepted "hostile aerial targets at dawn today."

The Israel Defense Forces said on Wednesday that it launched more strikes on the southern Lebanese city of Tyre, targeting what it claimed was "infrastructure" and weapons used by Hezbollah to attack Israeli forces operating in the south of the country.

The latest round of strikes targeted "Tyre and several areas in southern Lebanon," the IDF said in a post to X.

Also on Wednesday morning, IDF spokesperson Avichay Adraee issued a new evacuation order for the south Lebanese towns of Houmin al-Fawqa and Ghassaniyeh, warning of imminent "decisive action" against alleged Hezbollah targets there.

Israeli strikes in southern Lebanon continue unabated despite a ceasefire agreed between Israeli and Lebanese leaders, which was rejected by Hezbollah.

Lebanon's Ministry of Public Health said on Tuesday that at least 3,666 people have been killed and 11,321 people injured by Israeli attacks in Lebanon since March 2.

Iran launched multiple missiles and drones following a series of U.S. strikes — but nearly all of them were intercepted, according to initial assessments that are ongoing, according to a U.S. official. There are no reports of harm to any U.S. personnel, and the official was not aware of any damage to U.S. locations in the region at this time.

Earlier Tuesday, officials in Kuwait said air defense systems there were intercepting "hostile aerial targets."

The Iranian barrage came after the U.S. announced a series of strikes on Iran in response to the earlier downing of a U.S. Army helicopter.

U.S. forces have "completed self-defense strikes" in Iran in response to the downing of a U.S. Army Apache helicopter, U.S. Central Command said in a statement on Tuesday.

U.S. forces struck Iranian air defense, ground control stations and surveillance radar sites near the Strait of Hormuz on Tuesday as part of the retaliatory strikes, CENTCOM said.

"The operation was a proportional response to recent attacks on U.S. forces and international commercial ships transiting regional waters," the statement said.

"U.S. forces remain vigilant and postured to defend against unjustified Iranian aggression," the statement said.
