BEIJING — At least 18 kindergarten kids and two adults were killed Wednesday when a school bus with just nine seats but crammed with 64 people crashed on its way to class in western China, state media reported.

Authorities blamed overloading for the accident in which the bus collided head-on with a truck in China's Gansu province, Xinhua News Agency said.

News of the crash ignited public anger across China, highlighting an underfunded education system that especially shortchanges students in remote areas.
