Another important point: One test, even a successful one, does not completely prove a missile's capabilities.
Russia's defence ministry later said the missile landed about 500 kilometres from its territory and posed no threat.

But he slammed the latest missile test as a "reckless provocation" after holding an emergency meeting with national security advisers.
According to Tokyo, the missile flew for roughly 30 minutes, traveling to a height of 1,240 miles before falling back into the sea. Tensions heightened in the Korean Peninsula in recent weeks amid speculation Pyongyang may conduct its sixth nuclear test sometime soon while the North's leader continued to threaten neighboring South and the US with its series of missile tests, some of which had recently failed.
But it said the North's missiles did appear to be able to leave and re-enter the atmosphere, which is crucial to developing intercontinental ballistic missiles (ICBMs), the Yonhap news agency reported.
"The only thing we need to hear from North Korea is that they are ending and ultimately dismantling their nuclear weapons and ballistic missiles program", Pence told CNN, adding that the United States will continue to exert pressure until this end is met.
The U.S. said it aims to pressure North Korea into dismantling its nuclear and missile programs through sanctions while remaining open to dialogue.
The White House has mooted talks with North Korea under the right conditions, which would include a halt in missile tests.
Sunday's test came less than a week after South Korea elected a new president, Moon Jae-In, who advocates reconciliation with Pyongyang and had expressed a willingness to visit the North to ease tensions.
There's also a political victory for North Korea.
Although there are still plenty of technical hurdles to be overcome, many analysts believe North Korea will eventually achieve Kim's stated goal of developing an ICBM that can reach the mainland United States.
But Jeffrey Lewis, director of the East Asia nonproliferation program at the Middlebury Institute of International Studies at Monterey in California, said at the time that there was an "even chance" that they were intercontinental ballistic missiles (ICBMs). Observers also labelled another failed missile test in late April a KN-17 although the launch location changed. But it's not an ICBM. If launched on a maximum trajectory, the latest missile could have flown about 4,500 kilometres, within range of the U.S. military base at Guam, according to aerospace engineer John Schilling.
But the US military said that the flight pattern was "not consistent" with an ICBM and did not threaten the United States.
On Sunday, Moon said that his administration would deal resolutely with North Korea's provocations in a bid to ensure that Pyongyang would not "miscalculate" the situation.
KCNA added that "U.S. mainland and Pacific operations" are within range of North Korean missiles.
North Korea's state media generally confirmed those estimates.
He added that that launch violates Security Council resolution, and said that Mr. Guterres calls on the DPRK to "ensure full compliance with its global obligations". But it called for restraint to avoid increasing hostilities in the area.
South Korea's presidential Blue House said in a statement on Monday that special envoys would be sent to the US, China, Russia, Japan, and Germany to meet with high-ranking officials there and discuss how to develop firmer ties.
"If the United States dares opt for a military provocation against the DPRK, we are ready to counter it", it said.
The press statement from the U.N.'s most powerful body said its 15 members agreed to "take further significant measures including sanctions, in line with the council's previously expressed determination". Write to us in the Comments Section.
