A roaming herd of 15 wild elephants is on the move again after resting for a day in a patch of forest on the outskirts of the city of Kunming in southwest China, resuming a year-long, 500-kilometre trek that has captured the public's imagination.

Drone photographs taken on Monday by the provincial forest fire brigade showed members of the herd sleeping in a clearing in the middle of a forest in the district of Jinning, which has been hit by heavy rain and thunderstorms.
