The missile launched by North Korea on Friday was closely tracked by the U.S. government and never threatened the United States, a military official said Sunday.

General Lori Robinson, commander of the North American Aerospace Defense Command and U.S. Northern Command, said Sunday the missile was never a threat to the country.

"North Korea's launch on Friday of an Intercontinental Ballistic Missile was detected, closely tracked, and determined not to be a danger to North America," she said in a statement. "However, this provocative launch served as yet another reminder of North Korea's continued threat to the United States and our allies with their missile program."

North Korea is again under close scrutiny after its second missile test of the month. The intercontinental ballistic missile tested on Friday could reach as far as Chicago, according to some estimates.

The U.S. has confused multiple operations in South Korea in response to the test and Robinson said the military would remain on guard against a further test.

"As the Commander responsible for defending the homeland, I want to assure our citizens that USNORTHCOM remains unwavering in our confidence that we can fully defend the United States against this ballistic missile threat," she said. "At NORAD and USNORTHCOM, we stand this watch each and every day."
