North Korea has defined South Korea as a “hostile state” in its constitution, driving a wedge deeper between the nations after Pyongyang stoked tensions earlier this week by blowing up its sections of roads that linked it to the southern part of the peninsula.

STORY: North Korea destroyed sections of roads and rail lines on its side of the heavily fortified border between the two Koreas on Tuesday...... in what South Korean officials have called a "highly abnormal" act and a violation of past inter-Korean agreements.

North Korea's state media reported on Thursday that road and rail links with South Korea are now completely blocked off after blasting large sections of them on Tuesday as legitimate action taken against "a hostile state" as defined by its constitution.
