North Korean leader Kim Jong Un berated "irresponsible" officials for failing to prevent damage from a tropical storm that swept through the Korean peninsula last week, state media said Monday. Tropical Storm Khanun, which battered Japan before taking a circuitous route towards the Korean peninsula, moved across North Korea early Friday bringing heavy rains to the South. Natural disasters tend to have a greater impact on the isolated and impoverished North due to its weak infrastructure, while deforestation has left it vulnerable to flooding.
