Donald Trump has said the US military is "locked and loaded" to deal with North Korea.
Trump's latest bullish statement comes after a week of steadily escalating tension between Washington and Pyongyang.
The US President has said his forces will respond with "fire and fury" to any aggression by Pyongyang, while North Korea has said it has a plan to launch missiles at the US territory of Guam.
Trump has taken a hawkish tone with North Korea ever since taking office in January, while the North Korean government has responded with repeated missile tests and propaganda videos showing the destruction of US targets.
Russian Foreign Minister Sergei Lavrov has waded into the diplomatic spat, saying that there is a "very high" risk that tension will escalate further between the US and North Korea.
