Senior aides of President Yoon Suk Yeol, including his chief of staff, offered to resign en masse Wednesday, the presidential office said, after the National Assembly blocked Yoon's surprise declaration of martial law.

They include Chung Jin-suk, the presidential chief of staff; National Security Adviser Shin Won-sik; and Sung Tae-yoon, chief of staff for policy, as well as seven other senior aides.

The resignation offer came after Yoon declared martial law Tuesday night, accusing the opposition of "anti-state forces" that paralyze the operation of the nation with impeachment motions and a downsized budget bill.

Yoon lifted the martial law following a unanimous vote by the National Assembly early Wednesday to demand the president repeal it. (Yonhap)
