The curfew was put in place on May 19 after riots and arson attacks across Bangkok and in at least six provinces in the wake of an army crackdown to remove anti-government protesters in the capital.
Thailand's cabinet has agreed to extend a night curfew in Bangkok and 23 provinces until May 29, deputy prime minister Suthep Thaugsuban said on Tuesday.
Suthep said the curfew, which will be in force between midnight and 4 am, was necessary to prevent more unrest, but would not be in place for seven days, as was announced on Monday.
"We have cut the timeframe from seven to four days because we want to limit the impact on the public," Suthep told reporters.
