The US has expanded its aerial offensive against Iran, hitting a city hosting a nuclear power plant, while Iran has responded with strikes on Bahrain and Kuwait, as diplomats insist talks are ongoing.

Iranian media on Monday reported strikes around Tabriz, believed to hold underground missile bases, as well as Bushehr, home to the country’s only operational civilian nuclear power plant as the US military said it had struck “military command centers, air defence and coastal surveillance sites, maritime capabilities, missile and drone launch sites and communications networks”.
