A group of elderly South Koreans have arrived in North Korea to meet relatives they have not seen since the Korean War of 1950-1953.

The war left the Korean peninsula divided and people who lived on the northern side were unable to leave.

The two Koreas, which are technically still at war, have organised reunion events before, but this is the first in three years.

The South Koreans were chosen by lottery - the oldest of them is 101.

A hundred people were chosen by each side to attend the reunion.

Some dropped out after realizing the relatives they had hoped to see were no longer alive, so in total there'll be 83 North Koreans and 89 from the South.

One woman, aged 92, told reporters she was going to be seeing her son for the first since the end of the war.

Lee Keum-seom said she lost track of her son, then aged four, and her husband in the panic of trying to flee.

"I never imagined this day would come," she told AFP. "I didn't even know if he was alive or not."

"I'm over 90 so I don't know when I am going to die," Moon Hyun-sook told Reuters. She was travelling to meet her younger sisters.

"I am very glad that I have been selected this time, I'm walking on air now."

The Korean War separated millions of people from their families.

These brief meetings are likely the last and only time many will see each other.

Over the years, at times of relative calm, the two Koreas have arranged for selected groups to visit each other. There have been 20 such events in the past 18 years.

Past reunions between brothers and sisters, parents and children and husbands and wives have been extremely emotional experiences.

The South Koreans are travelling by bus over the heavily guarded border to the Mount Kumgang tourist resort.

They will spend three days in North Korea but only be with their relatives for a few hours each day - in total, only 11 hours. Most of their visit will be heavily supervised.

Many of those divided by the war are very old

Many are bringing gifts like clothes, medicine and food for their relatives in the much poorer North.

"I've prepared for him some household medicine including digester and headache pills, nutritional supplements as well as some daily necessaries," 76-year old Lee Soo-nam, who was due to meet his older brother, told Reuters.

Several doctors and nurses are travelling with the group to set up an emergency medical centre for the elderly participants.

The event, which is facilitated by the Red Cross, is the outcome of a historic meeting between North Korea's Kim Jong-un and South Korean President Moon Jae-in at the border in April.

The two leaders met a second time in May, where they agreed to resume family reunions, and are expected to meet again in the coming weeks.

South Korea has also taken an active role in trying to broker talks between Pyongyang and Washington.

In June, Kim Jong-un met US President Donald Trump in Singapore where they pledged to work towards denuclearization, although there are doubts over how genuine the North is in its commitment.
