Thailand's weekly cabinet Tuesday decided to impose the Internal Security Act (ISA) during March 11- 23 to ensure law and order in a mass anti-government rally by the United front for Democracy against Dictatorship (UDD) group.

The ISA imposition will take effect in the whole area of capital Bangkok and Nonthaburi, which is next to Bangkok, Thai News Agency reported.

Deputy Prime Minister for Security Affairs Suthep Thaugsuban has been assigned to control security operations to be conducted by involved security agencies.

Also, the ISA law will be implemented in some districts of six other provinces nearby Bangkok.

The six provinces are Pathum Thani, Samut Prakan, Samut Sakhon, Chachoengsao, Nakhon Pathom and Ayutthaya.

And, the cabinet approved enforcement of 18 other related laws in a bid to support the ISA law, acting government spokesman Panitan Wattanayagorn said.
