China has executed a bus driver who stabbed 24 children at a school in Shandong, state media reports.
The spate of attacks has prompted public concern about school safety
Jia Qingyou was sentenced to death earlier this month in the eastern Chinese province for attempted murder and kidnapping, Xinhua reported.
Mr Qingyou injured the children with a kitchen knife at the local No. 1 Experimental Primary School on 20 September.
The attack was the third on schoolchildren in China in two months.
The spate of incidents prompted schools in the capital Beijing and other regions to provide professional guards to protect students, Xinhua said in a separate report.
The children hurt in the Shandong attack received mainly injuries to their arms and faces.
All were reported to be in a stable condition immediately after the incident.
In the same month, a man armed with a knife and homemade explosives attacked 28 children at a kindergarten in Suzhou, near Shanghai.
No fatalities were reported.
In August, a doorman stabbed 15 children and three teachers at a Beijing nursery. One child was killed.
No motive was given for the attack, but local media speculated the man was mentally unstable and feared he might be about to lose his job.
