About 30,000 protesters have launched a "people's coup" on Thailand's government, Reuters reports.
Prime Minister Yingluck Shinawatra was forced to flee a police compound after it was swarmed by protesters and multiple state agencies have been also been targeted.
Police fired teargas on protesters and troops are being sent to a government complex occupied by protesters since Thursday and the Finance Ministry, occupied since Monday.
"We have sent forces to these places to take back government property," national police spokesman Piya Utayo said on national television.
