Sounds of gunfire were heard while Thai troops were patrolling along the Thai-Cambodian border in Surin, but no unusual activity was detected, the Royal Thai Army said on Friday.
Army spokesman Maj Gen Winthai Suvaree said troops from Ranger Company 2603 under the Suranaree Task Force were on duty near boundary marker 18 in Kap Choeng district on Thursday when five gunshots were heard 600 metres away in an area controlled by Cambodian forces.
