Tens of thousands of South Koreans took to the streets of central Seoul today to celebrate the ousting of President Park Geun-hye.
They carried flags and candles and cheered jubilantly, a day after the Constitutional Court removed her from office over a corruption scandal which had consumed the nation for months.
Meanwhile, in a nearby grass square, a large crowd of Ms Park's supporters glumly waved national flags near a stage where organisers, wearing red caps and military uniforms, vowed to resist what they called a "political assassination".
Police were braced for violent confrontations between the two crowds after three people died and dozens were injured in clashes between police and Park supporters after the ruling on Friday.
Nearly 20,000 officers were deployed on Saturday to monitor the protesters, who were also separated by tight perimeters created by hundreds of police buses, a bizarre scene which reflected a saga has left the nation deeply split over its future.
The anti-Park protesters shouted "The candles have won!" and "Arrest Park Geun-hye!" as they began marching towards the presidential Blue House, where Ms Park continued to stay a day after her removal.
The Blue House said she would need more time to vacate as her aides are preparing for her return to her private home in southern Seoul. Ms Park has not made a public statement on her removal.
The court's decision capped a stunning fall for the country's first female leader. Ms Park rode a wave of lingering conservative nostalgia for her late dictator father to victory in 2012, only to see her presidency crumble as millions of furious protesters filled the nation's streets.
The ruling allows possible criminal proceedings against the 65-year-old - prosecutors have already named her as a criminal suspect - and makes her South Korea's first democratically elected leader to be removed from office since democracy replaced dictatorship in the late 1980s.
It also deepens South Korea's political and security uncertainty as it faces existential threats from North Korea, reported economic retaliation from a China furious about Seoul's co-operation with the US on an anti-missile system, and questions in Seoul about the Trump administration's commitment to the US-South Korea security alliance.
South Korea must hold an election within two months to choose Ms Park's successor. Liberal Moon Jae-in, who lost to Ms Park in the 2012 election, currently enjoys a comfortable lead in opinion polls.
Kim Yong-deok, the chief of the National Election Commission, said on Saturday that the election would be managed "accurately and perfectly" and urged the public to participate in a vote that would "determine the fate of the Republic of Korea", referring to South Korea's formal name.
The Constitutional Court accused Ms Park of colluding with longtime confidante Choi Soon-sil to extort tens of millions of dollars from businesses and letting Choi, a private citizen, meddle in state affairs and receive and look at documents with state secrets. Those allegations were previously made by prosecutors, but Ms Park has refused to undergo any questioning, citing a law that gives a sitting leader immunity from prosecution.
It is not clear when prosecutors will try to interview her.
Prosecutors have arrested and indicted a slew of high-profile figures over the scandal, including Choi and Samsung's de facto chief, Lee Jae-yong.
Ms Park's lawyer, Seo Seok-gu, who had previously compared her impeachment to the crucifixion of Jesus Christ, called the verdict a "tragic decision" made under popular pressure and questioned the fairness of what he called a "kangaroo court".
Some of Ms Park's supporters reacted with anger after the ruling, shouting and hitting police officers and reporters with plastic flag poles and steel ladders and climbing on police buses.
Police and hospital officials said three people died while protesting over Ms Park's removal, including a man in his 70s who died early on Saturday after collapsing near the court.
