Thousands of anti-government protesters in Bangkok marched towards the city's revenue offices in their latest move to try to bring the government to a standstill.
Suthep Thaugsuban, one of the protest leaders, on Thursday urged followers to march to offices of the revenue department, noting that other government agencies had already been forced by the protesters' sieges to move to temporary premises or allow employees to work at home.
The marches appeared to be a way to maintain momentum amid a decline in the number of protesters who have blocked key intersections in Bangkok for four days in an attempt to shut down the government of Prime Minister Yingluck Shinawatra.
The demonstrators, who call themselves the People's Democratic Reform Committee, have sealed off other government buildings and ministries, as well as blocking major road junctions.
Although the demonstrations have been mostly peaceful, there have been random acts of violence including gunshots in the middle of the night at protest venues.
On Wednesday night, a small explosive device was hurled into the residence of protest leader Issara Somchai Issara, damaging part of a motorcycle in the garage, according to Police Col. Pong Sangmurin.
Since the latest wave protests started in November, eight people have been killed and more than 450 have been injured.
