South Korean lawmakers have voted to revise the rules around martial law, now barring any attempt to obstruct lawmakers from entering the National Assembly, BBC reported.

This comes after former President Yoon Suk Yeol's short-lived martial law order last December, which plunged the country into a political crisis.

As military forces gathered in front of the the National Assembly that night, lawmakers had to scale the walls to vote down Yoon's order.

The amendment on Thursday also bans the military and police from entering the National Assembly without the approval of its speaker, according to BBC.
