North Korea has fired a suspected ballistic missile into the sea, officials in South Korea and Japan said, shortly before Pyongyang’s representative told the United Nations the country had the “righteous right” to test weapons because of the “hostile” policies directed against it. Al Jazeera quotes North Korea’s UN envoy, Kim Song, as saying that they “are just building up [their] national defence in order to defend [them]selves and reliably safeguard the security and peace of the country,” pointing out that the US had nearly 30,000 troops stationed in the South and that there had been no formal treaty to end the Korean War. If the US gave up its hostility, North Korea would “respond willingly at any time”, Kim told UN delegates in his speech.
