South Korea's military says North Korea has begun removing some of the loudspeakers used to broadcast propaganda across the border between the two countries.

North Korea's move appears to be a positive reaction to the overtures from newly elected South Korean President Lee Jae Myung, who had campaigned on improving inter-Korean ties.

South Korea dismantled some of its own loudspeakers earlier this week. It had halted broadcasts along the demilitarised zone shortly after Lee took office in June - prompting a similar response from its neighbour.

South Korean broadcasts had often featured K-pop songs and news reports while the North played unsettling noises, such as howling animals.

In a statement on Saturday, South Korea's military said it had "detected North Korean troops dismantling propaganda loudspeakers in some parts along the front line from this morning".
