WASHINGTON (Reuters) - The missile North Korea fired early on Tuesday was likely an intermediate-range ballistic missile (IRBM) and further analysis was underway to determine whether it was a success or failure, two U.S. officials said.

The officials, speaking on the condition of anonymity, said the missile appeared to be a KN-17, or Hwasong-12, according to initial data.

According to the Pentagon, an IRBM has a range of between 1,500 and 3,000 nautical miles (1,726 miles to 3,452 miles/ 2,778 km to 5,556 km).

President Donald Trump warned on Tuesday that “all options are on the table” as the United States considers its response to North Korea’s firing of a ballistic missile over northern Japan’s Hokkaido island into the sea early in the Asian day.

The Pentagon said that diplomacy was still the preferred option.

“While all options are on the table, diplomacy is still in the lead,” Pentagon spokesman Colonel Robert Manning told Reuters.
