Rescue workers rush an injured woman to hospital following a car bomb attack at a business area in the Thai-Malaysian border district of Sungai Kolok, Narathiwat province, southern Thailand, on July 20, 2012.

Eight people were injured after a bomb exploded outside a commercial building in southern Thailand on Friday morning, The Bangkok Post reports. 

Authorities said the explosives were hidden in a pick-up truck outside a computer company in Sungai Kolok, Reuters reports. Three of the company's owners were injured escaping from the top floor of the building, authorities said. Another vehicle and two motorcycles were also destroyed in the blast that spread to nearby buildings.

At least 5,000 people have been killed in southern Thailand since 2004 in violence attributed to Muslim separatists.
