Ljubicic said that the ministry was still waiting for the confirmation of the driver's identity, which should be sent through diplomatic channels from Washington.
Zoran Sirocic and Marinko Les, another two Croatian truck drivers who were detained in US-run prisons in Iraq, have been released according to "first-hand information", Ljubicic said, adding that this report could not be officially confirmed yet.
The ministry official went on to say that the information on Sirocic's release came from his father. Sirocic was allegedly imprisoned in Falluja following a scuffle with US marines.
