The official Xinhua news agency said (today/ Tuesday) that the students died Monday after lighting the fire at a secondary school in Dingbian county in Shaanxi province.

Carbon monoxide poisoning in the winter months is common in rural areas of northern China. Local residents sometimes burn coal to keep warm when temperatures drop.
