By Hyunsu Yim, Eduardo Baptista and Minwoo Park SEOUL (Reuters) -Supporters of impeached South Korean President Yoon Suk Yeol are adopting "Stop the Steal" slogans popularised by U.S. President-elect Donald Trump supporters and said they hoped the incoming president would help their embattled leader.

Tensions ran high near the residence of impeached South Korean President Yoon Suk Yeol Thursday, as rival protesters clashed and hundreds of supporters formed a blockade to prevent his imminent arrest.

Authorities sought on Friday to execute an unprecedented arrest warrant for impeached South Korean President Yoon Suk Yeol, evading a crowd of protesters but facing off with security forces inside his residence.
