SEOUL—Two Japanese women were among the 26 foreign nationals confirmed dead in the Halloween party stampede in the downtown Itaewon district here on Oct. 29, the Japanese Embassy said.

The death toll had risen to 154 as of the morning of Oct. 31, the South Korean government said, adding that 103 of the fatalities were people in their 20s, 30 were in their 30s, and 11 were teenagers.

Thirty-three of the 149 injured in the crush were in serious condition, the government said.

The Itaewon nightlife district has become a popular spot for Halloween festivities among young people from around South Korea and overseas.

More than 100,000 people were estimated in the area at the time of the disaster on Oct. 29.

The nightmare is believed to have occurred when waves of people poured into a narrow alley, leading to a phenomenon known as “crowd crush,” which occurs when many people are pressed together.

South Korean media are questioning whether the authorities took proper security and crowd-control measures.
