Hello everyone and welcome to Ammanpur. Here's what's coming up.

We always have the authorization to defend American interest.

As Iran threatens to break out of uranium limits set by the nuclear deal,

America considers a full range of options in response to attacks on shipping.

Where will this current standoff end? Iran's ambassador to

Britain joins me for an exclusive interview and top US diplomat William Burns

weighs in. In Hong Kong, protesters won't back down even after the chief

executive suspends that controversial extradition law. They want her to resign.

I'll speak to Crow Democracy Activist Nathan Law.

Also, America's Poet Laureate dives into her family's past

and America's troubled racial history.

Our Walter Isakson talks to Tracy program everyone. I'm Christina Montpur in London. The

Trump administration says there is quote no doubt Iran is behind last week's

tanker attacks in the Gulf of Oman.

And as a leading Republican senator threatens the, quote,

fire and fury of the US military could be unleashed,

the saber rattling is getting harsher on both sides.

America's European allies say they have yet to see credible evidence to support those US claims.

And the owner of one of the tankers, the Japanese tanker,

questions the American account of what

happened but President Donald Trump leaves little doubt where he stands.

Well Iran did do it and you know they did it because you saw the boat. I guess one of the mines didn't explode and it's probably got essentially Iran written all over it.
