Five children were hurt at a school in north-eastern China when a man attacked them with a hammer, before killing himself.
The BBC reports it was the third such incident in China in three days.
The man grabbed two children before setting himself on fire at the pre-school in Shandong province's Weifang city.
The children were pulled to safety, and all five - plus an injured teacher - were said to be stable in hospital.
Xinhua news agency reports the man was a farmer. The motive for the attack is not yet known.
On Thursday, 28 children and three adults were attacked by an unemployed man with a knife at a nursery school in Jiangsu province, eastern China.
Five of the children were taken to hospital in a critical condition.
The day earlier, 15 pupils and a teacher were wounded by a former teacher - who was on sick leave - at their primary school in Guangdong province.
Earlier on Wednesday, a doctor convicted of stabbing eight children to death in Fujian province in March was executed.
