North Korea is a country which now has "nothing to lose," a top official warned on Monday, in a statement rebuffing U.S. President Donald Trump for recent remarks in which he warned leader Kim Jong Un not to escalate mounting tensions between the two countries.

In comments carried by the Korean Central News Agency (KCNA), Kim Yong Chol, a senior official on the DPRK ruling party’s Central Committee and Chairman of the Korea Asia-Pacific Peace Committee, levied a series of insults against the U.S. President, lambasting him as a "frivolous and pitiful old man."
