North Korea has been raising the level of threats by repeatedly holding drills simulating tactical nuclear attacks on the pretext of joint military exercises by South Korea and the United States, South Korean unification ministry said Wednesday.
In a report submitted to a parliamentary committee session, the ministry said the North has posed a "blatant" nuclear threat to its enemies by unveiling smaller nuclear warheads and testing various weapons.
"The North has continued to maintain its confrontational stance against the South and the U.S., while deepening its ties with China and Russia," the ministry was quoted by South Korean Yonhap news agency as saying.
The ministry added North Korea remained unresponsive to an inter-Korean liaison communication channel for the sixth straight day Wednesday, without specifying any reasons.
