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 U.S. Navy’s 5th Fleet, Saudi state television and local media reported Sunday, just days after the kingdom normalized relations with Israel.

Details about the claimed plot remained scarce Sunday 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 U.S. remain high after the Trump administration claimed to have reinvoked all United Nations sanctions on Tehran over its nuclear program — something disputed by other world powers. The militants reportedly sought revenge for the U.S. drone strike that killed Iranian Gen. 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 U.N. 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.
