Key Points
Constitutional Court to decide Yoon's impeachment on Friday
14,000 police personnel deployed in Seoul
Political tensions escalate over martial law controversy
Foreign embassies warn citizens about potential demonstrations
The notice came as the top court is set to rule on Yoon's impeachment over his brief imposition of martial law on December 3, Yonhap news agency reported.
"In connection with the Constitutional Court's verdict on the impeachment of President Yoon, US citizens should anticipate large-scale demonstrations and an increased police presence," the embassy said in a posting on X.
"Avoid areas where demonstrations are taking place, and exercise caution in the vicinity of any large crowds, gatherings, protests, or rallies," it said.
The advisory follows a similar notice issued by the Chinese Embassy in Seoul the previous day, in which it called for its citizens to take caution regarding safety and security.
The Chinese Embassy warned of "possible extreme incidents" and advised its people to "keep their distance from" and "not participate in, stay near, or watch" political demonstrations near the court and other areas in Seoul.
Earlier South Korean police have decided to deploy some 14,000 personnel in Seoul, according to sources familiar with the matter on Tuesday, as the Constitutional Court is poised to rule on South Korean President Yoon Suk Yeol's impeachment case.
The court said it will deliver its verdict on whether to dismiss or reinstate Yoon over his failed martial law bid on Friday. For months, political polarisation has deepened between supporters and opponents of Yoon's impeachment over his failed martial law bid.
