By Jack Kim SEOUL (Reuters) -South Korean opposition parties raised a motion to impeach acting President Choi Sang-mok on Friday, the majority Democratic Party said, in a move likely to escalate recent political strife in the country.

Thousands of South Koreans on Saturday filled the streets of downtown Seoul in massive rival rallies for and against impeached President Yoon Suk Yeol, as the Constitutional Court nears a decision on whether to formally remove him from office over his imposition of martial law in December.

South Korea’s Constitutional Court could soon rule whether to dismiss or reinstate impeached conservative President Yoon Suk Yeol.
