"As far as I know, representatives of the Investigative Committee returned to Moscow yesterday. They have accomplished part of current tasks within the investigation – examination of materials of Central African investigators, additional questioning of witnesses and obtaining information from a phone and a laptop that were left [after the attack on journalists]," Tokmakov said.
The diplomat noted that the results of the investigators' work on the ground would show whether there was a need to go there again.
The Russian Investigative Committee has already opened a criminal investigation into the case.
The Russian Foreign Ministry said the preliminary information showed that a robbery was the motive for the killing of the three journalists.
