A court in South Korea has issued an arrest warrant against suspended president Yoon Suk Yeol over his attempt to impose martial law on 3 December.

The warrant comes after Yoon, who is being investigated for abusing his power and inciting an insurrection, ignored three summonses to appear for questioning over the past two weeks.

Yoon’s legal team has called the warrant “illegal and invalid” and said they would challenge it in court.

South Korea has been in political crisis since the short-lived martial law declaration, with Yoon and a successor both impeached by the opposition-dominated parliament.
