Thai government has outlined security measures ahead of the Inter Parliamentary Union Assembly which starts on Saturday, the day the red shirts plan their mass rally.
Government spokesman Panitan Wattanayagorn said the security authorities discussed the red shirts' revised plan for Saturday which may affect the IPU meeting which starts on Saturday until April 1.
The discussion was made although the protesters have promised not to surround and block the meeting venue. More than 1,000 participants from 153 countries will attend the meeting at the Centara Grand Hotel.
The security meeting agreed to cooperate with organisers and the police to work together in providing security for the international meeting.
They agreed to set up 13 checkpoints at key areas after series of explosions occurred.
