North Korea has threatened to attack its neighbour if it feels threatened.
North Korea has in recent days threatened the U.S. with nuclear war and rehearsed drone attacks on South Korea, prompting Washington, to be involved in military drills with the South.
Park Geun-hye, South Korea’s first female President marked the third anniversary of the sinking of a South Korean warship that killed 46 sailors by calling on the impoverished North to abandon its nuclear ambitions to save its starving people.
The South, backed by an international commission, blames a North Korean torpedo attack, although Pyongyang denies it was responsible.
“The owner of Cheongwadae South Korea’s presidential office had better watch her tongue,” North Korea’s official KCNA news agency quoted a spokesman for the Committee for the Peaceful Reunification of Korea as saying.
North Korea has made no secret of its hatred for Park and earlier this month referred to the “venomous swish” of her skirt.
Tension between the two Koreas has risen sharply since the North conducted its third nuclear test in February, days before Ms. Park took office.
It was a move that triggered new sanctions against Pyongyang.
North Korea regularly attacked Ms. Park’s predecessor, Lee Myung-bak, with bellicose rhetoric.
It referred to Mr. Lee, who cut off aid to Pyongyang during his five years in office, as a “rat-bastard;” and shot and
hanged him in effigy.
