US sub sinks Iranian warship in Indian Ocean, Hegseth says

US Secretary of Defense Pete Hegseth has said an American submarine sank an Iranian warship in the Indian Ocean, BBC reported. 

He said the ship was sunk by a torpedo on Tuesday, and that it died a "quiet death".

Trump threatens to halt US trade with Spain over military bases, defence spending

U.S. President Donald Trump threatened to impose a ​full U.S. trade embargo on Spain on Tuesday after the European and NATO ally refused to let the U.S. military use its bases for missions linked to strikes on Iran, Reuters reported. 

"Spain has been terrible," Trump told reporters during a meeting with German Chancellor Friedrich Merz, adding that he had told Treasury Secretary Scott Bessent to "cut off all dealings" with Spain.

"We're going to cut off all trade with Spain. We don't want anything to do with Spain," he added, according to Reuters. 

Iran's strikes on Gulf states may widen war against Tehran, analysts say

Iranian airstrikes on Gulf states could push them into a broad coalition aligned with the United States and widen the war against Iran, Middle East analysts said, after attacks on ports, cities and oil facilities in a vital energy-producing region, Reuters reported. 

By striking at the Gulf’s economic lifelines ​in its response to U.S. and Israeli airstrikes on Iran, Tehran may be driving wary Gulf states closer to Washington and towards coordinated action against the Islamic Republic, analysts said.

The aim of the strikes against six Gulf states, all of which are U.S. allies and host American military bases, was to ensure those countries put pressure on U.S. President Donald Trump to halt the war, but Iranappears to have miscalculated, they said, according to Reuters.
