Trump says world 'has to be watching' the violence in Iran

President Donald Trump said Tuesday that he supports the demonstrations in Iran and urged the world to watch the Iranian government's violent effort to quash protests that he says have killed "thousands of people."
Speaking in London, where he is attending the NATO leaders summit, Trump said, "Iran is killing thousands and thousands of people right now as we speak."
He added they were killed "for the mere fact that they're protesting," and he called it a "terrible thing."
Trump was mum on what, if anything, the US could do in response to the violence, but he said, "I think the world has to be watching."

The president also sent out a tweet that said: "The United States of America supports the brave people of Iran who are protesting for their FREEDOM. We have under the Trump Administration and always will!"
