The government has asked the international community to cooperate in Seoul's efforts to discover the truth about a North Korean soldier's killing of a South Korean tourist at the North's Mount Geumgang resort last week.

A diplomatic source said Wednesday that he understands the South Korean government has asked its allies to cooperate in the proposed investigation of the fatal incident.

The source said that consultations with the allies had just begun and would take a couple of days to progress, while refusing to reveal the names of the countries.

In a related move, Seoul has reportedly briefed the United States, China and Japan on the incident, requesting that they prompt North Korea to accept the South's proposal of a joint probe.
