A tweet [ko] directing people to this fake blog post received quite some attention on April Fools’ day. Looking like a legit news article, the post says that North Korea announced that it is now an Islamic state and it includes detailed claims such as:

Kim Jong-un ‘asserted ‘every previous leader of North Korea were actually Muslim prophets, and so is Kim Jong-un himself’ and ‘Islamic leaders were highly offended by Kim Jong-un’s announcement.’
