Saudi Arabia's civil defence issued early warnings for the cities of Al-Kharj and Yanbu on Saturday morning, urging residents to be alert to a 'potential danger.' However, officials later announced that the danger had passed in both areas, without specifying what triggered the alerts. The announcements were reported by Reuters. The warnings came amid heightened tensions in the region. A US official told Axios that Iran had launched a ballistic missile targeting an American military base in Saudi Arabia, marking the first direct attack by Iran on the kingdom in four months. The attack underscores the ongoing friction between Iran and the US-backed Saudi coalition, which has been involved in conflicts in Yemen and elsewhere. No further details were provided about the nature of the threat in Al-Kharj and Yanbu. Al-Kharj is a city southeast of Riyadh, while Yanbu is a port city on the Red Sea. The quick all-clear suggests the situation was managed without incident. Saudi Arabia and Iran have been regional rivals for years, with tensions spiking after attacks on oil facilities and tankers. The latest missile strike is a reminder of the persistent instability in the region. Authorities have not confirmed whether the warnings were related to the missile attack. Authorities continue to monitor the situation, and residents have been advised to remain vigilant. The civil defence has not released further statements.
