Support for impeached ex-President Yoon is mobilized by thousands.

• Thousands protest in Seoul against former President Yoon Suk Yeol’s removal from office over his failed martial law declaration.

• South Korea’s Constitutional Court ruled on Friday to remove Yoon over his attempt to subvert civilian rule.

• The long wait for the ruling has heightened tensions, fueling far-right support for Yoon and rival rallies.

• Yoon defended his martial law attempt as necessary to root out “anti-state forces” and North Korea’s threats.

• Despite the protests, Yoon received support from extreme religious figures and right-wing YouTubers who used misinformation to court support for him.
