A Chinese media report says stray artillery shells from Myanmar wounded five people in the border county of Zhenkang in Yunnan Province on Wednesday.

China's foreign ministry said last month that Myanmar's military and ethnic minority militants had agreed on a temporary ceasefire through Beijing's mediation. But fighting is believed to be continuing.

A video distributed by Reuters shows clouds of dust rising from near a road and an apparently injured person lying on the pavement.

Foreign ministry spokesperson Wang Wenbin said at a news conference on Thursday that China had urged the relevant forces to prevent a recurrence.
