Seven South Koreans were rescued right after the accident and seven others were confirmed to be dead, with 19 missing.

On Saturday evening, a body believed to be one of the South Koreans missing was retrieved from a location that was some 22 kilometers away from the sinking site.

"The body retrieved by a police patrol ship was confirmed by a joint South Korea-Hungarian identification team to be a South Korean woman in her 20s," the government response team dealing with the deadly accident told reporters.

This brings the number of identified bodies from the sinking to 19, leaving seven others still missing.

Meanwhile, South Korean Foreign Minister Kang Kyung-wha requested the Serbian government's possible support in searching for the bodies, as the country borders Hungary, the ministry said.

Kang made the remarks during her visit to Belgrade, where she held meetings with Prime Minister Ana Brnabic, Foreign Minister Ivica Dacic and Interior Minister Nebojsa Stefanovic, it said. (Yonhap)
