Two security guards have reportedly been killed after a suicide bomb attack at the US embassy in the Turkish capital.
An Associated Press journalist reported seeing a body in the street at a side entrance of the embassy in Ankara.
Another journalist Ilnur Cevik told Sky News: "There was a huge bang which really shook everywhere."
He was in his car about 400 metres away from the US embassy when the reported blast happened.
Mr Cevik said he thought there were "a lot of injuries" as he "saw lots of ambulances and I thought there was something really serious".
