Prime Minister Yingluck Shinawatra on Monday night invoked the internal security law in Bangkok, Nonthaburi, Samut Prakan's Bang Phli district and Pathum Thani's Ladlumkaew district.
In a special TV broadcast, Yingluck said her government has no choice but to use the ISA after the anti-government protesters stepped up their protests by invading, seizing many government buildings and destroying the assets including the front gates. The protesters also cut off electricity and water supplies in those buildings, the moves that would affect officials and people in general.
