The main road linking Bahrain and Saudi Arabia was closed due to Iranian threats of possible retaliation for the attack on their bridges and railway infrastructure, the Associated Press reported on Tuesday.
Alongside the decision to close the route, Kuwait's Interior Ministry urged its citizens to stay indoors and near a protected area from Tuesday midnight until Wednesday as a preemptive measure against possible widespread Iranian attacks.
"The Ministry of Interior urges citizens and residents to remain in their homes and avoid going out, except in cases of utmost necessity, from 12:00 midnight on Tuesday, April 7, until 6:00 a.m. on Wednesday, April 8, as a precautionary measure," read the statement.
The measure aims to "safeguard everyone's safety, strengthening the level of prevention, and enabling security authorities to perform their duties with high efficiency."
Iran threatens bridges in the region after IDF infrastructure attack
The preventive decision by Kuwait and Bahrain comes as Iranian-linked groups shared a list of bridges and transport infrastructure that would be targeted as a response to the latest IDF attack on Iran's railways.
According to Turkey's state-run Anadolu Agency, citing IRGC-linked Tasmin Agency, Iran will target the Sheik Jaber Al-Ahmad Al-Sabah Sea Bridge in Kuwait, the King Fahd Causeway linking Saudi Arabia to Bahrain, the Sheik Zayed Bridge and Sheik Khalifa Bridge in the United Arab Emirates, as well as the King Hussein Bridge, Damia Bridge, and Abdoun Bridge in Jordan.
Additionally, Tasmin previously reported, citing military sources, that Saudi Arabia's Aramco infrastructure, alongside the Yanbu processing sites and the UAE's Fajairah pipeline, would become targets if the US or Israel attacked Iran's energy infrastructure.
Aramco is the main oil company in Saudi Arabia, while the port of Yanbu is the only port that fully operates and wasn't halted by the closure of the Strait of Hormuz.
