Trump warns Iran will pay 'many times over' for deaths of US soldiers

President Donald Trump has vowed to punish Iran for the deaths of US soldiers, saying Tehran would pay "many times over".

His warning came on Monday, several hours after he had said the latest US strikes that hit Iran "very hard" were in honour of three American soldiers killed recently - two in Jordan and one in Iraq.

The US military said the strikes - conducted for the ninth consecutive night - had hit military and communications sites to "further diminish" Iran's attacks on ships in the Strait of Hormuz.

Iran said it had hit sites in Bahrain and Syria, and also targeted US aircraft in Jordan. President Masoud Pezeshkian later said Iran was fighting a "full-scale war" with the US.

Tehran said diplomatic messages were still being exchanged by both sides through intermediaries, despite a collapse of a ceasefire.

Late on Monday, Jordan's military said it had shot down three Iranian missiles, as sirens sounded across the country warning of incoming fire.

Bahrain said drones launched by Iran had targeted its air navigation systems, but traffic remained unaffected.

On the US strikes, Iran's semi-official Tasnim news agency reported that several cities had been hit including Tabriz, Chabahar, Konarak, Bandar Mahshahr and Bandar Imam Khomeini.

There were also Iranian state media reports that two oil tankers had exploded as the vessels tried to cross the strait.

Iran's Islamic Revolutionary Guard Corps (IRGC) said the tankers were going through what it called an "unsafe and hazardous southern route" of the strait and "exploded and were brought to a halt".

The IRGC added that the strait "will not be safe for the transit of petrochemical products, nor even a single drop of oil and gas" as long as the US strikes continue and that it will respond with a "punitive operation".
