N. Korea demands detailed 'explanation' from Seoul over drone incursion

North Korean leader Kim Jong Un's powerful sister has demanded a detailed "explanation" from Seoul over a drone it accused South Korea of flying over its territory, state media reported Sunday.

The North alleged on Saturday that a craft crossed from the South Korean border county of Ganghwa into the North Korean city of Kaesong in early January, and released photos of wreckage from the drone it claimed to have shot down.
