The shock execution of Kim Jong-un's uncle Chang Song-thaek has left the region in a "grave and unpredictable" situation, according to South Korea's President Park Geun-hye.

Mr Chang was allegedly killed for planning a coup. North Korea has been keen to emphasize it is business as usual in the wake of his death.

North Koreans living in South Korea say they have heard of a rise in indoctrination sessions, possibly in response to a shift in public sentiment against Kim Jong-un.

Lucy Williamson reports from Seoul.
