The US military conducted strikes against Iran for the 13th night amid escalating clashes over shipping routes, following Houthi rebel attacks on two Saudi oil tankers in the Red Sea. Explosions were reported in Iranian coastal areas, and international oil prices surged above $100 a barrel. The US aims to secure the Strait of Hormuz, while the Houthis threaten further disruption. President Trump warned of severe military retaliation against Iran and the Houthis if attacks continue. Diplomatic efforts are underway, but tensions remain high, with Iran reporting casualties from renewed US airstrikes.
