Two white cloth banners with a message telling soldiers to get out of the area and declaring support for the Barisan Revolusi Nasional (BRN) separatist movement were found hanging at separate spots on a roadside near Ban Laweng in tambon Choeng Khiri of Narathiwat's Si Sakhon district on Monday morning.
The message on each of the banners read: "Soldiers get out. Support BRN." It was written in red in the Thai language.
District police and soldiers from the 49th Ranger Regiment were sent to examine the area.
