North Korea has warned South Korea of “unexpected consequences” if it lights up a Christmas tree-shaped tower near their tense border.
The North’s state-run Uriminjokkiri website said it would amount to a form of “psychological warfare”.
Seoul’s annual tradition of lighting up a Christmas tree tower was suspended in 2003 following a warming of ties.
However, the South lit a tower last year as relations deteriorated between the neighbours.
The Associated Press quotes a defence ministry official as saying the South has agreed to allow Christian groups to light a further two towers this year.
