From Jonathon Burch, Reuters:  A suicide bomber from a far-left group killed a Turkish security guard at the U.S. embassy in Ankara on Friday, blowing the door off a side entrance and sending smoke and debris flying into the street.

The attacker blew himself up inside U.S. property, Ankara Governor Alaaddin Yuksel said. The blast sent masonry spewing out of the wall and could be heard a mile away.

Interior Minister Muammer Guler said the bomber was a member of a far-left group. The U.S. State Department said it was working with Turkish police to investigate what it described as "a terrorist blast".

Islamist radicals, far-left groups, far-right groups and Kurdish separatist militants have all carried out attacks in Turkey in the past. There was no claim of responsibility.

"The suicide bomber was ripped apart and one or two citizens from the special security team passed away," said Turkish Prime Minister Tayyip Erdogan, who was attending a ceremony in Istanbul when the blast happened.

"This event shows that we need to fight together everywhere in the world against these terrorist elements," he said. . . .

U.S. Ambassador Francis Ricciardone emerged through the main gate of the embassy, which is surrounded by high walls, shortly after the explosion to address reporters, flanked by a security detail as a Turkish police helicopter hovered overhead.

"We are very sad of course that we lost one of our Turkish guards at the gate," Ricciardone said, thanking the Turkish authorities for a prompt response.  (photo: NTV)
