Egypt has been dragged into the Middle East war after drones hit a US-owned gas storage tanker at a Mediterranean port, British maritime security firm Ambrey said on Wednesday.A statement from Egypt's petroleum ministry confirmed a fire at the port of Damietta, but made no mention of a drone ​attack and did not provide a cause for the incident.Port services firm Inchcape said in a separate message two ​gas tankers had caught fire at Damietta.The drone hit floating storage tanker Energos Winter, causing a ⁠fire that spread to another vessel, Gaslog Salem, three trading sources familiar with the incident said. Two separate security sources ​said the likely cause of the blast was assessed as a drone strike.The Energos Winter was reportedly struck by an ​unidentified projectile on its starboard side, causing a fire that was extinguished.It was unclear who was responsible for the incident, which occurred shortly after Iran carried out a missile attack against US forces in Jordan, and Washington and Saudi Arabia ​struck Iran-backed paramilitary groups in Iraq.The latest strikes in Iraq and Egypt threatened to draw more Middle Eastern countries into ​the conflict, after the Iran-aligned Houthis in Yemen last week declared a naval blockade on Saudi Arabia.

A temporary ceasefire agreement in June collapsed amid renewed fighting over the strait, which Iran says it now controls. The joint US-Saudi attacks marked the first time Riyadh has publicly joined strikes alongside Washington.Iraq's Popular Mobilisation Forces, powerful Iran-backed paramilitary groups incorporated into the Iraqi security forces, said at least 20 members were killed and ​32 wounded in US-Saudi strikes targeting several bases across Iraq.Iraqi men shouted 'Death to America!' as they carried the bodies of slain fighters in body bags. Washington and Riyadh said they struck Iran-backed armed groups in Iraq in retaliation for drone attacks on Saudi oil targets ‌launched from Iraq. After ⁠the joint attacks, Saudi Arabia's defence minister met with Vice President JD Vance in Washington on Wednesday to urge the Trump administration not to escalate the conflict further by attacking Yemen's Houthis and carrying out additional strikes against the Iran-aligned militias in Iraq, two sources told Reuters.One of the sources added that such escalation would open the door to 'major unknown risks'.The White House and Saudi embassy in Washington did not immediately respond to a request for comment.US officials have privately cautioned that resuming major combat operations against Iran would carry risk given the negative impact on stocks of munitions.The Centre for Strategic and International Studies, a Washington-based think tank, estimated this week that the US military has fewer than 1,000 ​Patriot interceptor missiles and fewer than 250 THAAD interceptors - two ​key air defence systems.Though Iran denies its forces have ⁠directed strikes from Iraqi territory, Iranian newspaper Hamshahri reported that four Iranian Revolutionary Guards advisers had been killed in the strikes on Iraq.
