Suspected Islamic rebels detonated two bombs and opened fire on authorities riding in an armored railway car early Sunday in southern Thailand, wounding at least 19 people, police said. The armored car was making a routine inspection of track near the Sungai Kolok district station in Narathiwat province when the bombs exploded, tearing apart the track and overturning the car, police Lt. Nathiwat Deekaew said. The bombs were triggered by a mobile phone at around 6:15 a.m., just minutes after the train departed from the station, he added. Insurgents hiding nearby then ambushed the passengers, leaving at least 11 police officers and eight railway officials wounded, he said, adding it was not known how many passengers were on the train. A gunfight ensued but ended after about 10 minutes. No rebel casualties were reported.
