The explosions at the nuclear test site deep in the mountains of the North's sparsely populated northeast were centred on three tunnels at the underground site and a number of buildings in the surrounding area. North Korea held a closing ceremony afterward with officials from its nuclear arms program in attendance. A man in Seoul walks past a TV broadcasting a news report on the dismantling of a nuclear testing site in North Korea. A tunnel on the eastern side of the facility had already been shut down after an initial nuclear test in 2006. North Korea said the demolition of the facility did not cause any leakage of radioactive materials or have any "adverse impact on the surrounding ecological environment."
