N Korea in 'sea of flame threat'
North Korea has said it would attack South Korean loudspeakers and other propaganda facilities along its border, warning it could even turn Seoul into a "sea of flame".
The General Staff of the Korean People's Army made the threat in a declaration carried by the official Korean Central News Agency.
It said the North would launch an all-out military strike to blow up any propaganda facilities along its border and that its retaliation would be "a merciless strike foreseeing even the turn of Seoul ... into a sea of flame".
Tensions have risen since Seoul blamed the North last month for the sinking of a navy ship that killed 46 sailors. North Korea denies involvement.
