Developing: 'Terrorist Blast' Outside U.S. Embassy In Turkey

There's been an explosion near an entrance to the U.S. embassy in Ankara, Turkey, according to multiple news reports.

Reuters says at least one person was killed. The Associated Press writes that police are saying there have been two deaths. The BBC notes that there are reports this may have been the work of a suicide bomber. It adds that:

"Dozens of ambulances and fire engines rushed to the scene after the explosion, in an area which is home to diplomatic missions. According to Turkish broadcaster NTV, the explosion caused no damage inside the embassy itself."

At 7:15 a.m. ET, there were no statements about the incident on either the embassy's Facebook or Twitter pages.

As is often the case in the early hours after incidents such as this, the news is likely to shift as more information becomes available. We'll keep an eye on developments.
