The Irish embassy in Seoul is urging all Irish citizens living in South Korea to register their contact details with them.

It comes as reports suggest North Korea is preparing for a fourth nuclear test amid growing tensions on the Korean peninsula.

Around 1,000 Irish people live in South Korea but the Department of Foreign Affairs has said there is no cause for immediate concern.

Conor O'Reilly, Chairperson of the Irish Association of Korea lives just south of Seoul, also said there's no need to panic.
