British PM warns world action if Hormuz is shut

British Prime Minister David Cameron warned that the "whole world" would take action if Iran closed the Strait of Hormuz, in a television interview during a visit to Saudi Arabia on Friday.

"It is in the interests of the whole world that those straits are open and, if there was any threat to close them, I am sure the whole world would come together and make sure they stayed open," Cameron told Al-Arabiya television.

The New York Times reported late on Thursday that the United States has used a secret channel to warn Iran's leaders against closing the Strait of Hormuz, saying that doing so would provoke a US response.
