Volkswacht Bodensee - South Korea president declares martial law

The National Assembly was sealed late on Tuesday night and helicopters were seen landing on the roof, as army chief General Park An-su took charge as martial law commander and immediately issued a decree banning "all political activities".

Hundreds of protesters gathered outside parliament demanding to be let inside as police guarded the building and special forces attempted to enter.

Democratic South Korea is a major ally for the United States in Asia, and a spokesman for the US National Security Council said Washington was "monitoring the situation closely".

Yoon's stunning announcement -- South Korea's first declaration of martial law in more than 40 years -- came as his his party and the opposition bicker over the budget.

"To safeguard a liberal South Korea from the threats posed by North Korea's communist forces and to eliminate anti-state elements plundering people's freedom and happiness, I hereby declare emergency martial law," Yoon said in a live televised address to the nation.

Yoon did not give details of the North's threats, but the South remains technically at war with nuclear-armed Pyongyang.

"With no regard for the livelihoods of the people, the opposition party has paralysed governance solely for the sake of impeachments, special investigations, and shielding their leader from justice," Yoon added.

"Our National Assembly has become a haven for criminals, a den of legislative dictatorship that seeks to paralyse the judicial and administrative systems and overturn our liberal democratic order," Yoon said.

With martial law imposed, all military units in the South have been ordered to strengthen their emergency alert and readiness postures, Yonhap news agency reported.

China, a key ally of North Korea, urged its nationals in the South to stay calm and exercise caution.

The decree by martial law commander Park also banned "actions that deny or seek to overthrow the liberal democratic system, including the spread of fake news, public opinion manipulation, and false propaganda".

The president labelled the opposition, which holds a majority in the 300-member parliament, as "anti-state forces intent on overthrowing the regime".

Yoon described the imposition of martial law as "inevitable to guarantee the continuity of a liberal South Korea," adding that it would not impact the country's foreign policy.

"I will restore the country to normalcy by getting rid of anti-state forces as soon as possible," he said, without elaborating further other than the martial law in place.

He described the current situation as South Korea "on the verge of collapse, with the National Assembly acting as a monster intent on bringing down liberal democracy".

Yoon's People Power Party and the main opposition Democratic Party are bitterly at odds over next year's budget.

Opposition MPs last week approved a significantly downsized budget plan through a parliamentary committee.

The opposition has slashed approximately 4.1 trillion won ($2.8 billion) from Yoon's proposed 677 trillion won budget plan, cutting the government's reserve fund and activity budgets for Yoon's office, the prosecution, police and the state audit agency.

Yoon, a former prosecutor, accused opposition lawmakers of cutting "all key budgets essential to the nation's core functions, such as combatting drug crimes and maintaining public security... turning the country into a drug haven and a state of public safety chaos."

The imposition of emergency martial law comes as Yoon's approval rating dropped to 19 percent in the latest Gallup poll last week, with many expressing dissatisfaction over his handling of the economy and controversies involving his wife, Kim Keon Hee.
