The Iran-backed Houthi movement has claimed a missile attack on the Saudi city of Jizan, sharply escalating tensions after Riyadh launched airstrikes against rebel targets in Yemen. The exchange opens another volatile front in a conflict already stretching across the Middle East. The latest tit-for-tat attacks come as regional shipping lanes face mounting disruption and Washington weighs its next move in an increasingly dangerous confrontation with Iran. Saudi Strikes Trigger Swift Response The Houthis said the attack on Jizan was retaliation for Saudi airstrikes carried out on Friday against military targets in Yemen. The group accused Riyadh of a "dangerous escalation" and warned that its actions would "not go unanswered". A Yemeni security source said Saudi strikes hit a naval base in the port city of Hodeida and a military camp on Kamaran Island. The Saudi-led coalition said it targeted Houthi military infrastructure threatening commercial shipping in the Red Sea, adding that its operation had concluded. Shipping Routes Under Growing Pressure The confrontation follows Houthi claims that they attacked two Saudi vessels in the Red Sea this week, with Saudi Arabia confirming one of the incidents. Coalition spokesman Turki al-Maliki said the strikes were a direct response to attacks on commercial shipping. The renewed violence adds pressure to global maritime trade. Alongside the Houthi campaign in the Red Sea, Iran's blockade of the Strait of Hormuz has intensified fears over the security of two of the region's most critical shipping routes. Trump Keeps Military Option Open US President Donald Trump said he had not yet decided whether to authorise major strikes against Iran, insisting diplomatic talks with Tehran were becoming more serious. His comments followed reports that he had met senior advisers to discuss possible large-scale military action. Trump also said he trusted assurances from Chinese President Xi Jinping and Russian President Vladimir Putin that neither country was supplying Iran with military support. Conflict Spreads Across the Region The wider crisis continues to deepen. US embassies across the Middle East have warned Americans that opportunities to leave the region could become increasingly limited, while Iran has urged civilians in neighbouring countries to stay away from bases hosting US troops. The US military said it disabled another merchant vessel attempting to breach its blockade of Iranian ports, while regional security incidents multiplied. Iraqi officials reported drones being intercepted near the US base in Irbil, and Iran claimed attacks on US military facilities in Kuwait and Bahrain, claims that had not been confirmed by US Central Command.
