Police in Moscow have discovered the body of a two-year-old boy, the son of a North Korean diplomat stationed in the city.

The boy vanished a week ago after wandering off from an embassy picnic in a park in central Moscow.

His body was discovered in a stream in a western area of the city and identified by his father.

Police said the boy's death appeared to have been a tragic accident with no criminal motives involved.

There had been earlier speculation that he might have been kidnapped.
