Donald Trump has said the US will begin blockading the Strait of Hormuz in an attempt to take control of the strategic waterway from Iran, following the collapse of peace negotiations between the two countries in Pakistan.
The US president also threatened to bomb Iran's water treatment facilities, power plants and bridges, repeating an earlier threat, if Tehran does not agree to abandon its nuclear weapons programme – the key sticking point between the two sides.
Trump's surprise announcement of a blockade came after 21 hours of face-to-face peace negotiations between the US and Iran in Islamabad collapsed on Sunday morning.
JD Vance, the vice-president and head of the US team, said Iran had refused to give up the possibility of developing nuclear weapons, while the Iranian delegates said Washington needed to do more to win their trust.
