Japan will send three police experts to help a U.N. team investigate the February car-bombing assassination of former Lebanese Prime Minister Rafik Hariri, according to sources.

The dispatch of three officers of the MPD's identification section will mark the first time Japan has sent police officers abroad to take part in an international investigation spearheaded by the United Nations in line with a terrorist incident.

Japan has sent police officers abroad in connection with other types of crime, including identification section members who took part in international emergency relief missions in large-scale disasters and supervised the use of identification equipment.
