A reported movement involving a US nuclear-powered submarine near Gibraltar has drawn attention amid rising tensions between Washington and Tehran after President Donald Trump’s sharp criticism of Iran’s response to ceasefire negotiations.&nbsp;According to the Gibraltar Broadcasting Corporation, USS Alaska, an Ohio-class nuclear-powered submarine operated by the US Navy, was seen arriving near Gibraltar on Sunday evening under heightened security measures.&nbsp;The broadcaster published photographs showing a 200-metre exclusion zone established around the South Mole “until further notice”. The report also stated that a team of Royal Marines was believed to have arrived on the Rock aboard RAF transport aircraft.&nbsp;The reported submarine movement quickly fuelled speculation online, with several social media commentators claiming USS Alaska was heading towards the Mediterranean Sea. However, there has been no official confirmation or evidence supporting those claims.&nbsp;The Ohio-class fleet is regarded as one of the most powerful components of the US Navy’s strategic arsenal. According to GBC, the fleet includes 14 ballistic missile submarines and four guided missile submarines. Each vessel is approximately 171 metres long and can displace close to 18,750 tonnes while submerged, making them among the largest submarines in US naval service.<h2>Trump attacks Iran’s ceasefire response</h2>Also read: <a href="https://www.wionews.com/world/massive-oil-spill-off-iran-s-kharg-island-satellite-images-show-huge-slick-near-key-oil-export-hub-1778304662118">Massive oil spill off Iran’s Kharg Island?

The USS Alaska, a nuclear-powered submarine, arrived at Gibraltar on May 10, 2026, amid heightened security. This follows President Trump rejecting Iran’s ceasefire proposal as “totally unacceptable,” signaling increased strategic pressure.
