The accident happened at Longfeng Private Primary School at Mingguan Town, Yongnian County, at about 6 p.m. when the pupils were dining, a county government spokesman said.

The injured were receiving treatment at a local hospital. The county government had relocated all the students to other schools to continue their studies on Wednesday night.

The government also issued a notice Wednesday night, asking all the middle and primary schools in the county to suspend classes for two days to check building safety.

Snow continued to hit many parts of north China Thursday, causing highway and airport closures.

About 700 passengers were stranded at the airport. The airport staff are cleaning up the snow on the runway.
