周六，韩国联合参谋本部暂未确认该发射物为弹道导弹还是其他类型的武器。
South Korea’s Joint Chiefs of Staff on Saturday did not immediately say whether the weapon was a ballistic missile or another type of system.
此次发射正值两国关系紧张之际——上个月，朝鲜埋设的地雷导致三名韩国士兵受伤。
The test came amid heightened tensions between the countries following land mine blasts that injured three South Korean soldiers last month.
韩国及以美国为首的联合国军司令部均认定，这些爆炸事件系朝鲜地雷所致。
South Korea and the U.S.-led U.N. Command have said the blasts were caused by North Korean mines.
