• Trump shares video with racist imagery of Obamas

Top Democrats in Congress have condemned Donald Trump for sharing a racist video of Barack and Michelle Obama that depicts them as apes.

Hakeem Jeffries, the House minority leader, called the president a “vile, unhinged and malignant bottom feeder”. He noted that the Obamas were “brilliant, compassionate and patriotic Americans” who “represent the best of this country”.

• US and Iran talks brought back from the brink after White House relents on move to Oman

It is the first time the US and Iran have sat down for face-to-face negotiations since June last year, when Israel launched attacks on Iran that sparked a war marked by tit-for-tat airstrikes, with the US also joining the fray. It effectively ended the US-Iran talks that were held in the weeks prior to the conflict aimed at reaching a nuclear peace agreement.

More recently, Donald Trump has been threatening to strike Iran for more than a month and just last week warned that an “armada” of US warships had reached the Persian Gulf. This recent clash began after Trump said he would strike Iran if it killed protesters during mass antigovernment demonstrations that swept the country last month. Human rights groups say thousands of people were killed during the brutal government crackdown on those protests.
