Twenty-eight people have died and hundreds have been injured in a wave of attacks by giant hornets in central China, according to reports.
Victims described being chased for hundreds of metres by the creatures and stung as many as 200 times.
Most of the attacks in the past three months were in remote, rural, wooded areas in southern Shaanxi, the province's China Business newspaper reported.
In the city of Ankang alone, 18 people have died from the stings, health official Zhou Yuanhong told Associated Press. People in the cities of Hanzhong and Shangluo have also been injured.
The insects' highly toxic stings can lead to anaphylactic shock and renal failure. An official from Ankang's disease control centre urged people to seek medical help if they received more than 10 stings, and warned that emergency treatment was required for those stung more than 30 times.
