DUBAI, United Arab Emirates (AP) — Bahrain broke up a plot by militants backed by Iran to launch attacks on diplomats and foreigners in the island nation home to the US Navy’s 5th Fleet, Saudi s tate television and local media reported yesterday, just days after the kingdom normalised relations with Israel.

Details about the claimed plot remained scarce last night as Bahrain’s Interior Ministry and its state media did not publicly acknowledge the arrests. Bahraini government officials, who routinely claim breaking up plots by militants backed by Iran, did not respond to a request for comment.

However, it comes as tensions between Iran and the US remain high after the Trump administration claimed to have reinvoked all United Nations sanctions on Tehran over its nuclear programme — something disputed by other world powers. The militants reportedly sought revenge for the US drone strike that killed Iranian Genral Qassem Soleimani in January, something long threatened by his colleagues in Iran’s paramilitary Revolutionary Guard.

The Saudi state TV report aired footage of what appeared to be police raiding a home with a hidden passage. The footage showed assault rifles and explosives, apparently seized in the raid.

Nine militants have been arrested while another nine are believed to be in Iran, the Saudi state TV report said.

Iranian state media acknowledged the reports of the Bahraini arrests, but no official commented on them. Iran’s mission to the UN did not immediately respond to a request for comment.

Authorities uncovered the plot after finding an explosive on the street believed to have been planted to target a “foreign delegation,” the pro-government Bahraini newspaper Akhbar Al-Khaleej reported, citing the Interior Ministry. The ministry accused the Revolutionary Guard of supporting the militants, who also had surveilled oil sites and military bases, the newspaper said. The militants also planned on assassinating bodyguards of Bahraini officials, the newspaper said.

It wasn’t clear when all the arrests and alleged plots took place, as the Akhbar Al-Khaleej report referred to incidents dating as far back as 2017. The newspaper linked the militants to the al-Ashtar Brigade, a Shiite group that has claimed responsibility for a number of bombings and attacks in Bahrain, including two that killed police. The group has been sanctioned by the US.

Bahrain is home to the 5th Fleet, which patrols the waterways of the Mideast. Officials have worried in the past that the sailors and marines attached to the base in Manama could be targeted, as well as others who make up the 7,000 American troops there. Cmdr Rebecca Rebarich, a spokeswoman for the 5th Fleet, declined to comment and referred questions to the Bahraini government.

Bahrain, an island off the coast of Saudi Arabia, just last week normalised relations with Israel alongside the United Arab Emirates, in part over their joint suspicion of Iran.

Israel’s foreign ministry declined to comment on the reported arrests in Bahrain.

Iran under Shah Mohammad Reza Pahlavi had pushed to take over Bahrain after the British left the country, although Bahrainis in 1970 overwhelmingly supported becoming an independent nation and the UN Security Council unanimously backed that. Since Iran’s 1979 Islamic Revolution, Bahrain’s rulers have blamed Iran for arming militants on the island. Iran denies the accusations.

Bahrain’s Shiite majority long has accused its Sunni rulers of treating them like second-class citizens. They joined pro-democracy activists in demanding more political freedoms in 2011, as Arab Spring protests swept the wider Middle East. Saudi and Emirati troops ultimately helped violently put down the demonstrations.

Bahrain promised change after the protests. But in recent years, Bahrain has cracked down on all dissent, imprisoned activists, and hampered independent reporting on the island. Militant groups like the al-Ashtar Brigade have launched small, sporadic attacks amid that crackdown.
