|Four injured at Samsung's Viet plant riot
Workers building a factory for Samsung in northern Vietnam have fought with security guards and set fire to motorbikes.
State media reports said the unrest today followed an argument between a guard and a worker who turned up late at the complex.
Local official Duong Ngoc Long said police restored order after three hours.
Video posted on YouTube showed workers throwing rocks at police in riot gear as thick black smoke billowed from parts of the complex.
Long said four people were injured.
Samsung and other tech companies are increasingly moving factories to Vietnam, where labor costs are cheaper than in neighboring China.
