Trump says US will blockade strait of Hormuz as Iran peace talks fail

Iran warns move would breach ceasefire as US president also repeats threats to strike critical infrastructure

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 in the aftermath of failed peace negotiations between the countries in Pakistan.

The US president also threatened to bomb Iran’s water treatment facilities as well as its power plants and bridges, repeating an earlier threat, if Tehran did not agree to abandon its nuclear weapons programme – the key sticking point between the two sides.
