IRAN - US Defense Secretary Pete Hegseth says a US submarine sank an Iranian warship in the Indian Ocean with a torpedo.

It's thought around 180 people were on board the Iris Dena - 32 were rescued, and Sri Lankan authorities tell the BBC 80 bodies have been found so far. At the same news conference, Chairman of the Joint Chiefs of Staff, Gen Dan Caine, says the US will strike "progressively deeper into Iranian territory". The UK is sending a warship to the eastern Mediterranean after attacks on a British base in Cyprus - but it is not expected to set off this week. Meanwhile, Israel says it hit "security headquarters" across Tehran, as US-Israeli airstrikes continue in Iran. "It's getting worse and worse every day," one man in Tehran tells the BBC. A three-day funeral ceremony for ex-Supreme Leader Ayatollah Ali Khamenei, due to start this evening, has been postponed. Israel is also hitting Lebanon - we speak to the owner of a Lebanese hotel that was hit. New attacks, apparently from Iran, have been reported in Saudi Arabia and Kuwait, while Turkey says "Nato defences" shot down an Iranian missile. (BBC)
