Major government and media websites in South and North Korea were shut down for hours Tuesday on the 63rd anniversary of the start of the Korean War.
Seoul said experts were investigating attacks on the websites of the South Korean presidential Blue House and prime minister’s office, as well as some media servers.
The North Korean websites that shut down Tuesday included those belonging to the national airline, Air Koryo, the Rodong Sinmun newspaper, the North’s official Uriminzokkiri site and Naenara, the country’s state-run Internet portal. All but Air Koryo were operational a few hours later.
It wasn’t immediately clear who was responsible. North and South Korea have traded accusations of cyberattacks in recent years.
The shutdowns came on a war anniversary that both countries were marking with commemorations. North and South Korea are also gearing up for the 60th anniversary of the end of the fighting July 27.
