Shortly after President Donald Trump warned the US might "militarily complete the job", Iran early on Sunday launched missiles and drones on US military sites in Kuwait and Bahrain, continuing a series of escalating attacks.
The US military said earlier it had struck Iran again, hours after a tanker was hit in the Strait of Hormuz, the world's most important energy shipping route, which Iran had largely cut off for most of the conflict.
The 14-point US-Iran interim agreement was meant to halt the fighting, which the US and Israel started on February 28, and reopen the strait to shipping while talks began on more deep-seated issues, such as Iran's nuclear programme.
One round of mediated talks, led by Vice President JD Vance and Iran's Parliamentary Speaker, Mohammad Baqer Qalibaf, was held in Switzerland a week ago and Washington then waived sanctions on Tehran, but the fighting and recriminations have since resumed and intensified.
"There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started," Trump posted on social media.
About an hour after Trump's post, the Kuwaiti army said its air defences were responding to "hostile" missile and drone attacks, while sirens sounded in Bahrain, according to that country's interior ministry.
Iran's Islamic Revolutionary Guard Corps said its navy and air forces had launched joint missile and drone operations targeting US military sites in Kuwait and Bahrain in response to recent US strikes against Iran.
A US official, confirming the attacks on the facilities, said the situation was still unfolding but there were no reported US casualties or major damage to US sites in the Middle East at this time.
