Thousands of anti-government protesters are out on the streets of the Thai capital, reviving their whistle-blowing, traffic-blocking campaign to force the resignation of the country's prime minister.

Protesters are marching from Bangkok's main Lumpini Park, taking six different routes through the city center. They have reiterated demands for Yingluck Shinawatra's elected government to yield power to an interim appointed council that would introduce vaguely defined anti-corruption reforms.

The march Saturday comes after a lull in anti-government street rallies that started four months ago and amid growing concern of violence between supporters and opponents of Yingluck, who has refused to step down.

Her government has come under growing threats of legal action that could force it from office, including an impeachment case in which she must submit her defense on Monday.
