South Korea fires at suspected drone at border with North amid missile crisis

By Ju-min Park and Christine Kim SEOUL (Reuters) - South Korea's military fired warning shots at a suspected drone from North Korea on Tuesday amid tension over Pyongyang's latest missile test which drew international condemnation and a warning from China. The incursion came with tension already high on the Korean peninsula after the North's test-launch of a ballistic missile test on Sunday which Pyongyang said proved advances in its pursuit of building a nuclear-tipped weapon that can hit U.S. targets. The United States has been trying to persuade China, North Korea's lone major ally, to do more to rein in North Korea, which has conducted dozens of missile launches and tested two nuclear bombs since the start of last year, in defiance of U.N. Security Council sanctions and resolutions.
