North Korea is considering launching missiles on Guam, a U.S. island territory, according to a report Tuesday evening.

North Korea's military said, in a statement carried by state-run KCNA, it would carry out a pre-emptive strike against Guam if the U.S. provoked Pyongyang, according to a report from Reuters.

The U.S. has a THAAD defense system in Guam, which is 2131 miles to the southeast of North Korea, that is meant to help guard against a missile attack.

Earlier Tuesday, President Trump said he would unleash "fire and fury" on North Korea if it threatens the U.S. with its nuclear weapons program.

Trump's threat to North Korea came hours after Pyongyang escalated its criticism of the U.S. and threatened to conduct another missile test in response to sanctions the United Nations Security Council unanimously approved on Saturday.

North Korea test-fired its second intercontinental ballistic missile late last month, which some experts said may be capable of reaching parts of the U.S.

News reports Tuesday said an updated U.S. intelligence assessment found that North Korea has successfully produced a miniaturized nuclear warhead that can fit inside its intercontinental ballistic missiles.
