President Yoon Suk-yeol and first lady Kim Keon-hee attended a memorial Mass held Sunday at the Myeongdong Cathedral for the victims of the Itaewon crowd crush.

It was Yoon's third attendance in a religious service honoring the victims, following a Buddhist memorial service at the Joggye Temple in central Seoul on Friday and a church service organized by the United Christian Churches of Korea on Saturday.

During Sunday's Mass, Yoon was seen crossing himself and praying.

Unlike the two previous services, Yoon did not take the podium for a speech.
