Many red-shirt supporters arrived on motorcycles and in vans on Friday to challenge the anti-government protesters near the Chaeng Wattana rally site.
Tension rose at the site at 11am when the red-shirts arrived together with a sound truck. They announced through the public address system that that the rally at Chaeng Wattana was causing hardship to passenger van operators and local residents.
The red shirts formed their line about 100 metres from the barrier line of security guards of the People’s Democratic Reform Committee.
Gunfire was heard while the red shirts were confronting the PDRC guards, causing sending the motorcyclists and vans to flee before later regrouping.
Army officers near the scene rushed in to set up a line of barriers on the road to prevent the two sides from coming near each other. Police officers also joined the Army officers in trying to control the situation.
The situation eased at about 12:30pm when the two sides stepped back from the confrontation.
Earlier, at noon, an explosion was heard from the side of the Prapa Canal causing protesters and reporters to dash for cover behind the PDRC’s barrier.
