Turkey: deadly blast outside US embassy in Ankara

A blast outside the US embassy in the Turkish capital, Ankara, has killed at least two people, with reports that it was a suicide bomber.

Turkish media said the suspected bomber and at least one security guard had died in the explosion.

Dozens of ambulances and fire engines rushed to the embassy, in an area also home to other diplomatic missions.

Video appears to show damage to a checkpoint although reports say there was no damage inside the embassy.

US ambassador to Turkey Francis J. Ricciardone, Jr. told reporters the situation was "very sad".
