US Embassy in Turkey shut for unspecified 'security threat'

The US Embassy in Turkey will be closed today due to an unspecified security threat.
A statement posted on the embassy's web page on Sunday urged US citizens to avoid the embassy in Ankara as well as large crowds and to "keep a low profile."
The statement said the embassy will be closed "due to a security threat. The Embassy will announce its reopening, once it resumes services." It did not give details on the threat.
In 2013, a suicide bomber detonated an explosive in front of the US Embassy in Ankara, the Turkish capital. He killed himself and a Turkish guard. Turkish officials blamed the attack on domestic leftists.
