Ten primary school pupils in central China were stabbed on Monday, the first day of the new academic year, according to the local authorities.
The children were attacked at Chaotangpo Elementary School in Baiyangping, a town in Hubei province, local news portal hbenshi.com.cn reported.
A suspect was detained following the attack, although police have yet to release any further details.
A spokeswoman for Enshi Central Hospital confirmed that many of the injured pupils were being treated there, without disclosing any information about their condition.
Local police could not be reached for comment.
Knife attacks on schoolchildren are a regular occurrence in mainland China, with the perpetrators often saying they are motivated by a desire to take revenge on society.
Earlier this year, two pupils were killed in an attack at a school in Baijiaping in Hunan province, and in January a maintenance man in Beijing was detained over a hammer attack in which 20 pupils were injured.
