BANGKOK — Police fired tear gas Sunday at anti-government protesters armed with gasoline bombs who were trying to force their way into the prime minister’s complex and police headquarters.

On Saturday, the seventh day of protests, clashes between pro- and anti-government supporters turned violent around Ramkhamhaeng University, with at least three people killed overnight and dozens injured, according to police.

“We can’t take any more of this corrupt government,” said Adi Ngo, a protester, as demonstrators nearby tried to breach concrete barriers and razor-wire-lined police barriers around Thailand’s seat of government. “This government doesn’t obey the law.”

Anti-government leaders declared Sunday “victory day” in what they’ve termed a “people’s coup,” urging their supporters to take over 10 government offices, six television stations, police headquarters and the prime minister’s offices in a bid to undermine the government.

The protest movement, which fell well short of its Sunday “coup” objective, wants to overthrow the administration of Prime Minister Yingluck Shinawatra, whom they accuse of being a puppet for her older brother, Thaksin Shinawatra.

Thaksin Shinawatra remains in self-imposed exile after his 2008 conviction on corruption charges.
