US ambassador to Qatar resigns amid Gulf crisis

US envoy to Doha Dana Shell Smith has stepped down after serving three years as US ambassador to Qatar, but questions remain about the motive of her timely resignation.

The US ambassador to Qatar announced she is leaving her post in Doha, amid one of the worst diplomatic crisis involving US’ Gulf allies in years.

“This month, I end my 3 years as US Ambassador to #Qatar. It has been the greatest honor of my life and I’ll miss this great country,” Dana Shell Smith wrote on Twitter on Tuesday.

Smith did not say why she was stepping down, if she was staying within the diplomatic service or who would replace her.

In Washington, officials said the ambassador had made a personal decision to leave the post earlier this year after serving a normal three-year tour.

“Ambassador Dana Smith’s assignment as ambassador comes to an end this month and she will depart Qatar later this month as part of the normal rotation of career diplomats throughout the world,” a senior State Department official said.

“Her decision to leave the foreign service was made earlier this year. We wish her the best as she moves on from the Department of State.”

Smith’s departure comes amid criticisms of Washington sending out mixed signals over crisis pitting Gulf allies against one another.

It began when Saudi Arabia, the UAE and Bahrain cut ties with Qatar claiming that Doha supported extremist groups. Qatar strongly rejects the allegations.

US President Donald Trump has signalled his support for the Saudi-led move but other Washington officials have been more cautious and called for dialogue to end the crisis.

Qatar is home to al-Udeid, the largest US airbase in the region, which houses around 10,000 troops.

Smith was appointed ambassador to the Gulf emirate by Barack Obama in 2014.

Last month she appeared to express dissatisfaction with political events back home in another message posted on social media.

She took to Twitter in the hours after Trump’s dramatic sacking of FBI director James Comey, tweeting: “Increasingly difficult to wake up overseas to news from home, knowing I will spend today explaining our democracy and institutions.”

Smith said she will be launching her own personal Twitter account following her resignation.
