On Thursday night, the US launched a sixth series of aerial attacks on Iran. Iran responded with attacks on US targets in neighbouring Arab countries.
The US launched a wave of strikes against Iran for the sixth night in a row, its military said, as the two sides battled over control of the Strait of Hormuz.
US Central Command (Centcom) said the attacks were intended to "further degrade Iranian military capabilities", before saying it had boarded a vessel as part of its blockade of Iranian ports.
State media reported that the US had hit civilian infrastructure, including bridges, a train station and an airport. The BBC has verified an attack on one bridge to the west of Bandar Abbas in Hormozgan province.
Iran's Revolutionary Guards (IRGC) say they have retaliated by striking US maritime surveillance radar sites in Oman as well as targets in Kuwait and Bahrain. They also claim to have attacked a US special operations command centre in Syria.
The IRGC said the surprise attack at al-Tanf in Syria, near the border with Jordan, was in retaliation for the killing of Iranian soldiers two days ago. Neither Syria nor the US have commented on the claim.
Later on Friday, Jordan's military said it shot down three Iranian missiles with no casualties or damage reported.
Kurdish forces in Iraq also said eight drones were shot down over the Iraqi city of Erbil, with no casualties reported.
