The US embassy in Seoul said Wednesday the “situation remains fluid” following South Korean President Yoon Suk Yeol’s reversal of a martial law decree that sparked fierce backlash and demonstrations.

Axar.az reports that citing CNN, the embassy issued an advisory urging Americans traveling in the country to exercise caution and avoid areas where protests are taking place.

“Even demonstrations intended to be peaceful can turn confrontational and escalate into violence,” the embassy said in its alert.

It also said it would cancel all “routine consular appointments” for US citizens and visa applicants on Wednesday.

The US is among several countries, including the United Kingdom and China, that have urged their citizens traveling in South Korea to exercise caution after Tuesday’s upheaval.
