The leader of North Korea, Kim Jong Un, personally supervised the launch of two long-range cruise missiles on Wednesday, state media said.
State media on Thursday revealed that the weapons were equipped to carry tactical nukes and had already been deployed to North Korean army units.
Wednesday’s test included two long-range strategic cruise missiles, which travelled 2,000 kilometers (1,240 miles) over the sea before hitting their targets.
According to experts, cruise missiles travel at much lower altitudes than ballistic missiles, making them harder to detect and intercept.
