Meanwhile, Thai police has beefed up security at key government agencies and deployed officers on rooftops around rally sites to prevent incidents by third parties wanting to incite violence, a top police official has said.
Deputy Police Commissioner Pol Gen Worapong Chiewpreecha, deputy director of the Centre for Administration of Peace and Order, said police and troops were being deployed to guard key government offices such as Government House and Parliament.
He said late last night that officers would also be deployed on high-rise buildings in the area to watch out for possible attacks by third-party groups.
Police, he said, would also erect concrete barriers and barbed wire around key government offices, but would reduce the areas covered as protected zones.
