The DPRK means business, the North Korean news agency has just released this image of their artillery taking aim at Seoul:
More DPRK nonsense, even if they did shell Yeonbongfongdongtaepongdo, the ROK can reply with six times the accuracy and twice the firepower. I think Pyongyang is slowly starting to realise that the days of threatening the 'weak old South propped up by the US' are pretty much past, the south is not weak anymore.
