Chinese authorities say two students and a teacher were killed when a van plowed into a crowd outside a school on the outskirts of Beijing.
The Pinggu district government says the incident happened early Thursday as students were arriving for class at Machangying Elementary School. District spokesman Zhang Yiyang says the van's driver apparently lost control and plowed into students and others arriving at the school gates.
Authorities say at least 20 people were injured, 19 of them students. The driver, a man surnamed Liang from neighboring Hebei province, has been held for questioning.
School safety has long been a problem in China, with students crushed to death in stampedes, run down on their way to class and targeted by assailants.
