Fifteen primary school stu­dents fainted when running for a physical education exam in Preah Vihear province’s Rovieng district yesterday.

Authorities have not yet determined the reason. The students were hospitalised, and some of them had left hospital for home yesterday, said Ae Saro, Rovieng district governor.

Ae Saro said that there were about eight other students who felt dizzy, but they did not pass out, so they were left to rest at home.

A provincial education committee went to the school to examine the case, but have not released any results yet, said Ae Saro.
