Two children in the Mekong Delta's Bac Lieu Province were killed by hornet stings Sunday, while picking tamarinds, VnExpress reported Tuesday.
They had accidentally struck a nest of the stinging insects while picking the fruit. A local woman, Huynh Thi Ngoan, tried to save the boys and was stung as well.
Vo Dang Khoa, 10, and Huynh Ngoc Thoi, 11, were rushed to hospital but succumbed to their injuries later that night.
The boys were stung more than a hundred times, doctors say.
Ngoan survived her injuries.
