On Monday, 89 elderly South Koreans crossed the border into the North to attend the family reunions at the eastern scenic mountain resort of Kumgang, which were held for three days until Wednesday.

They met 185 people from the North found alive in the impoverished country.

A second round of reunions is set to take place from Friday through Sunday. A total of 83 North Korean people will meet their families living in the South. More than 330 South Koreans, mostly the elderly, will gather in the eastern city of Sokcho later Thursday, a day before traveling to Mount Kumgang by bus.

Their first meeting with the North Koreans is scheduled to start in the afternoon.

The South's related authorities are on alert for the possibility of a powerful typhoon having an impact to the event.

Typhoon Soulik is on track to sweep across the peninsula Friday, according to weather agencies.

Around 40 officials from the government, the Korean Red Cross and Hyundai Asan, a firm which built facilities in the region to help facilitate South Koreans' visits there, are double-checking the meeting venue and hotels, the Ministry of Unification said.

There are about 57,000 South Koreans wishing to reunite with their family members in the North. Before this week's reunions, the two Koreas had held 20 rounds of such events since their first inter-Korean summit in 2000. (Yonhap)
