A Japanese daily says the remains of eleven Koreans have been found at an airport construction site in Hokkaido during a search and excavation project in the region.

The remains are believed to be those of Koreans forced to work at the site during Japan's colonial rule of Korea.

The Asahi Shimbun reported Wednesday that the remains were unearthed over the past three days during the third phase of the excavation project, in which the remains of 30 people have been unearthed since 2005.

Some four-thousand Korean workers were reportedly sent to the construction site and 95 of them are believed to have died.

A Japanese civic group, which jointly conducted the excavation with Hanyang University, said that it requested the Japanese government conduct a DNA analysis of the remains in order to find the respective families of those who were unearthed.
