US ambassador to Qatar steps down after posting critical tweets about Trump

The US ambassador to Qatar has stepped down after posting critical tweets about Donald Trump's administration after he fired FBI Director James Comey.

Dana Shell Smith announced the move a week after several Gulf states cut diplomatic ties with the monarchy in Doha, citing concerns over their financial ties to Islamist groups including the Muslim Brotherhood. Saudi Arabia, Egypt, The Maldives, United Arab Emirates, Libya, and Bahrain won praise from Mr Trump for coordinating the anti-Qatari effort.

The President claimed foreign leaders had singled the country out for funding "radical ideology", prompting criticism over his failure to address similar allegations levelled at his Saudi allies. Smith, a long-standing member of the US foreign service, has not indicated whether the ongoing crisis or the Trump administration played any part in her move, which the US State Department insists is "part of the normal rotation of career diplomats throughout the world".

However when Comey was fired on 9 May she tweeted: "Increasingly difficult to wake up overseas to news from home, knowing I will spend today explaining our democracy and institutions.

"Diplomats explain & defend our political system.Can be tough when partisan acrimony so high, but there is still no greater country. #USA."

Smith - who was appointed as the head diplomat in Doha by former President Barack Obama three years ago - has since tweeted that "Qatar is a strong partner in combating terrorist financing", contradicting the US President's public claims that the country is "a funder of terrorism at a very high level". Egypt has long thought Qatar's support of Islamist groups Muslim Brotherhood was dangerous for their country.

Saudi Arabia also re-ignited tensions over Doha's alleged support for Iran, which they claim could act to destabilise the region. Last week Secretary of State Rex Tillerson asked that the nations in the anti-Qatari effort "ease the blockade against Qatar". However, just hours later Trump applauded the coalition and raised the possibility that the cutting of ties was due to his urging that Middle East countries more effectively address financing terrorists.
