Children injured in the attack are being treated in hospital

Eight pupils have been stabbed to death at a primary school in China's southern province of Fujian, local media say.

At least five other pupils are reported to have been injured in the knife attack at the school in the city of Nanping.

A man who allegedly had mental problems was arrested in connection with the attack, which happened as children were arriving at the school.

The school is now closed and the pupils have been sent home.

The suspect, said to be in his 40s, had worked at a community clinic.

Reports said passers-by and school guards managed to restrain him before police arrived. No motive has been given for the attack.
