SEOUL - The Republic of Korea (ROK) and the Democratic People's Republic of Korea (DPRK) agreed Tuesday to hold the reunion of Korean families, separated by the 1950-53 Korean War, late next month in the DPRK's Mount Kumgang resort, Seoul's unification ministry said.

The first family reunion in about one and a half years would be held at the gathering center in the scenic Mount Kumgang resort, located in southeastern DPRK, from Oct 20 to Oct 26, the ministry said in a statement.

About 100 people each from the two Koreas would meet their long- lost relatives during the upcoming event, the first since February 2014 when the last family reunion was held in Mount Kumgang on a similar scale.

The agreement came after more than 23 hours of marathon talks. The working-level Red Cross contact ended at 10:10 a.m. Tuesday ( 0110 GMT) after kicking off at 10:50 a.m. Monday.
