North Korea confirmed Monday that the weapon launched a day earlier was its most powerful missile tested since late 2017, state-run media reported, in a move that could mark an end to nearly four years of leader Kim Jong Un¡¯s self-imposed moratorium on longer-range tests.

Analysts said the missile in question was an intermediate-range ballistic missile (IRBM) after Japan and South Korea reported the launch Sunday. It was the nuclear-armed country¡¯s seventh round of weapons tests this month.

Both Tokyo and Seoul said the missile had reached an altitude of about 2,000 kilometers (1,245 miles) and flew roughly 800 km on a ¡°lofted¡± trajectory, meaning it had been launched at an angle to hit a high altitude while limiting its flight distance.
