Thailand’s army chief says the military is taking control of government, BBC reported.
The BBC’s Jonah Fisher, in Bangkok, says the move appears to confirm that a full-blown coup is under way.
The latest unrest began in the Thai capital late last year, when then-Prime Minister Yingluck Shinawatra dissolved the lower house of parliament.
Demonstrators have blockaded several areas for months.
On Tuesday, the military imposed martial law.
Earlier this month, a court ordered Ms Yingluck’s removal for alleged abuse of power.
Thailand has faced a power struggle since Ms Yingluck’s brother, Thaksin Shinawatra, was ousted by the military as prime minister in 2006.
