The King Fahd Causeway Authority said movements across the 25-kilometer bridge, the only road link between Saudi Arabia and Bahrain, were halted in response to security alerts issued through the kingdom’s early warning systems.

Saudi Arabia’s defense ministry said it had intercepted ballistic missiles aimed at the Eastern Province, without providing further details on the origin or scale of the attack.

The causeway is a critical transport and economic corridor linking Bahrain host to the U.S. Navy’s Fifth Fleet to the Arabian Peninsula, and its closure underscores rising regional risks tied to the ongoing conflict involving Iran.

The development comes as Donald Trump has set a deadline for Iran to reopen the Strait of Hormuz and agree to a ceasefire, warning of potential strikes on Iranian infrastructure, including bridges and power facilities, if demands are not met.

Regional tensions have intensified in recent days, with missile interceptions reported across Gulf states and increased security measures implemented to protect critical infrastructure and civilian areas.
