Iran launched a barrage of missiles at a trio of US allies in the Middle East early Thursday after American forces carried out a second round of airstrikes in response to Tehran’s “unwarranted and continued aggression.”

Bahrain, Jordan and Kuwait were targeted by the Islamic Republic, as happened a day earlier after an initial wave of US attacks.

All three gulf nations are hosts to US military forces, which were targeted in the strikes but were uninjured.

US Central Command successfully defended against the attacks, preventing the Iranian strikes from hitting the US bases, a military source told The Post.

Jordan said it intercepted 20 Iranian missiles fired toward an area that is home to a base hosting US troops, though no one was hurt.

Kuwait closed its airspace for several hours, but did not elaborate on any damage.

Bahrain’s Interior Ministry said an 11-year-old girl was hurt and cars and homes were damaged by debris from interceptions responding to the Iranian attack.

It came after US Central Command (CENTCOM) said its strikes, which lasted approximately four hours and ended shortly before dawn broke across Iran, targeted the theocratic regime’s “military surveillance capabilities, communication systems and air defense sites.”

Specifically, the combatant command struck missile and radar sites on the Iranian coast, a source familiar with US military operations said.

Explosions could be heard around the capital city of Tehran, as well as the port city of Bandar Abbas and other southern areas along the Strait of Hormuz.

Iran’s paramilitary Revolutionary Guard later said sites hit included a manufacturing complex, a military barracks and a local Guard base outside of Tehran.

President Trump claimed in an interview with Fox News chief foreign correspondent Trey Yingst that took place during the ongoing strikes that 49 Tomahawk missiles were launched at targets inside Iran, while American fighter jets took out radar and air defense systems around the Persian Gulf.

Trump also claimed that Iranian officials had directly asked him to stop the bombing while he was monitoring the operation in the White House Situation Room and vowed to “bomb the s— out of them tomorrow night” if Tehran did not agree to a US peace proposal.

The president said later Thursday a deal was about to be finalized and he’d hold off on further strikes.

The US wants Iran to give up its stockpile of nearly 1,000 pounds of highly enriched uranium, which is believed to be buried underground after the American military hit three nuclear sites last year.

Iran is refusing to give up the uranium and demanding relief from sanctions. It also wants the release of frozen assets even before a final agreement is in place, something Trump rejected.

Iran has insisted that any deal to end the war must also end fighting between its ally Hezbollah and Israel, a demand Israeli Prime Minister Benjamin Netanyahu has rejected.

A Qatari diplomatic delegation, negotiating in coordination with the US, left Tehran on Thursday morning after holding talks, according to an official with knowledge of the team who spoke on condition of anonymity to discuss the mediation.

Pakistan, meanwhile, expressed deep concern over rising tensions and urged both Iran and the US to adhere to the cease-fire, which has been in effect since April 8 and which Trump described to Yingst Wednesday night as “the most violated cease-fire in the history of the world.”
