North Korea says it has conducted tests of cruise robots with a range of 2,000 kilometers.
The launches come as the US and South Korea hold a simulated military exercise in Washington DC, meant to counter North Korean nuclear threats.
According to the state news agency KCNA, it is about four robots that flew for almost three hours. Unlike the ballistic robots that the country has at its disposal, the cruise robots will fly in ovals and figures of eight over the ocean.
