North Korea has fired an intercontinental ballistic missile (ICBM) but it failed mid-flight, says the South Korean military. The ICBM launch, the North's seventh this year, sparked an alert in Japan - but fell short, landing in the sea. Tensions are escalating amid fears the North will soon conduct a nuclear test. On Wednesday both Koreas fired missiles near each other's waters. The exchange saw the most number of missiles launched by the North in a single day.

韩国军方表示，朝鲜发射了一枚洲际弹道导弹，但在飞行途中失败。这是朝鲜今年的第七次洲际弹道导弹发射，此次导弹发射惊动了日本，但没有达到目的，导弹落在了海里。由于担心朝鲜很快会进行核试验，目前紧张局势正在不断升级。周三，朝韩两国都在对方海域附近发射了导弹。这次交火是朝鲜在一天内发射导弹数量最多的一次。

North Korea's multiple launches comes as the US and South Korea are staging their largest-ever joint air drills, which Pyongyang has strongly criticised as "aggressive and provocative". On Thursday North Korea fired a long-range missile at around 07:40 local time, according to a statement from South Korea's Joint Chiefs of Staff. A source confirmed with the BBC that it was an ICBM. It flew for about 760km and reached a height of around 1,920 km. But the launch was "presumed to have ended in failure", South Korea's military said.

朝鲜进行多次导弹发射的同时，美国和韩国正在举行有史以来规模最大的联合空中演习，对此，朝鲜强烈批评此举具有“侵略性和挑衅性”。根据韩国参谋长联席会议的一份声明，周四朝鲜在当地时间07:40左右发射了一枚远程导弹。一位消息人士向BBC证实，这是一枚洲际弹道导弹。它飞行了约760公里，达到了约1920公里的高度。但韩国军方表示，此次发射“被认为以失败告终”。
