Around 1,000 anti-government campaigners have forced their way into an army compound in Bangkok to protest against their country's Prime Minister. They are calling on the military to help topple the government.

"Protesters slammed opened the gate and are now in the army headquarters," a military spokeswoman said, adding that the army chief was not in his office.

Protests are also taking place elsewhere in Thailand's capital against Yingluck Shinawatra at her party's headquarters.

She is the sister of former leader Thaksin Shinawatra, who is widely thought to be the real power behind the government. 

He was ousted in a 2006 military coup but retains strong support from the rural majority in Thailand.

Yingluck Shinawatra survived a no-confidence vote in parliament on Thursday and urged the demonstrators to end their protests.

Protesters want Yingluck Shinawatra to go

She has been reluctant to use force to evict the opposition-led protesters for fear of escalating a tense political crisis and sparking bloodshed.

Security forces have done little to stop protesters who have spent the week seizing government buildings and camping out at several of them in an effort to force a government shutdown and get civil servants to join their rally.

Crowds of protesters have occupied the Finance Ministry since Monday and others remain holed up at a sprawling government complex that houses the Department of Special Investigations, the country's equivalent of the FBI.

On Thursday, the demonstrators cut power at Bangkok's police headquarters and asked police to join their side.

The protesters accuse Yingluck, 46, of serving as a proxy for her billionaire brother Thaksin Shinawatra - a former prime minister who was ousted in a 2006 military coup but retains strong support from the rural majority in Thailand.

Thaksin, who lives in Dubai to avoid serving a jail term for a corruption conviction he says was politically motivated, is a highly polarizing figure in Thailand.
