Four primary-school students were killed and at least 10 others wounded in Nong Bua Lamphu’s Muang district after a former school director slammed into them with his car while suffering an epileptic seizure behind the wheel.

Police said the accident happened at 9.20am as students from different schools were walking into the Nong Bua Lampu Pitthaya School to participate in an event for World Science Day, which wraps up tomorrow.
