Iran responded with missile and drone attacks targeting Bahrain, Jordan and Kuwait, countries hosting US military forces, further widening the regional conflict.

The Strait of Hormuz continues to be at the centre of the conflict, with Iran's earlier disruption of shipping prompting the US to reimpose a naval blockade amid rising tensions.

The US military said it disabled the Curacao-flagged oil tanker Belma after accusing it of attempting to breach the naval blockade while sailing towards Iran's main oil export terminal at Kharg Island.

American strikes targeted multiple Iranian military installations, including missile sites on Greater Tunb Island and a mechanized infantry brigade in Sistan and Baluchestan province, according to officials.

Iranian Parliament Speaker Mohammad Bagher Ghalibaf warned of a broader military confrontation if the US fails to honour the interim agreement, while the Revolutionary Guard threatened regional energy exports.

Escalating hostilities and uncertainty over shipping through the Strait of Hormuz pushed Brent crude prices above USD 85 per barrel, reflecting growing concerns over global energy supplies.

Iraqi Prime Minister Ali al-Zaidi condemned an intercepted drone attack on Irbil as regional tensions spilled beyond Iran, coinciding with his official visit to the United States.
