Turkey's Foreign Ministry says several of its nationals were killed Friday in an ambush in the northern Iraqi city of Mosul.

The ministry says the victims were security guards on their way to the Turkish embassy in Baghdad.  Four men escaped, two returned to southern Turkey, while two others reached Baghdad.

The ministry did not specify how many guards were killed, but reports earlier Friday of an ambush in Mosul said four people had been killed.  One of the victims was reportedly beheaded.

In another development, the U.S. embassy confirmed the name of an American kidnapped seven weeks ago when gunmen stormed a Saudi-owned catering company in Baghdad. Officials said they are working to free Roy Hallums and Filipino Roberto Tarongoy, who was also abducted.
