How do the relative reunions work in Korea?

More than 100 South Koreans have arrived in North Korea for reunions with their relatives - the first such events since 2010.

The reunions, which come after North Korea called for better relations between the two sides, are taking place from 20 to 25 February.

The reunions are highly emotional occasions. Families from both sides meet briefly at the events, before returning to their respective homes.
