San Francisco Frontiers - Kim Jong Un and daughter oversee North Korea's ICBM launch

The launch on Thursday -- Pyongyang's second ICBM test this year -- involved a Hwasong-17 missile, the official Korean Central News Agency reported, adding that it was fired in response to "frantic" US-South Korea joint military drills.

Photographs in the official Rodong Sinmun newspaper showed Kim watching the black-and-white Hwasong-17 -- dubbed a "monster missile" by analysts -- blast off into the sky.

Some of the images showed him watching the launch with his daughter -- never named by state media but identified as his second child Ju Ae by South Korean intelligence.

State media also released images showing the Earth from space, purportedly taken by a camera mounted on the ICBM.

KCNA said the launch "confirmed the war readiness of the ICBM unit", adding that it "had no negative impact on the security" of neighbouring countries.

South Korea had previously said the missile was fired on a lofted trajectory -- up instead of out, typically done to avoid overflying neighbouring countries.

Last year, North Korea declared itself an "irreversible" nuclear power, and Kim recently called for an "exponential" increase in weapons production, including tactical nukes.

Overseeing the Thursday launch, Kim said North Korea would "react to nuclear weapons with nukes" and called for "irreversibly bolstering up the nuclear war deterrent", according to KCNA.

He also highlighted the country's "rapid response posture... to cope with any armed conflict and war", KCNA said.

In theory, the Hwasong-17 ICBM can reach the continental United States, and with this latest launch, North Korea is trying to emphasise the advanced level of its weaponry, analysts said.

"With the photos of the Earth, Pyongyang seems to be trying to show that it can accurately hit any target the regime wants with its ICBM," Cheong Seong-chang, a senior fellow at the Sejong Institute, told AFP.

The next step will likely be North Korea firing the missile "at a normal angle", he said, which would demonstrate it can survive reentry into the atmosphere.

The Thursday launch -- Pyongyang's third show of force this week -- came as Tokyo and Seoul sought to thaw long-frozen ties to counter an increasingly aggressive North Korea.

South Korean President Yoon Suk Yeol flew to Japan Thursday to meet Prime Minister Fumio Kishida, the first such summit in 12 years.

North Korea fired two cruise missiles from a submarine on Sunday, followed by two short-range ballistic missiles on Thursday, as South Korea and the United States staged major military drills.

The allies have ramped up defence cooperation in the face of growing military and nuclear threats from North Korea, which has conducted a series of increasingly provocative banned weapons tests in recent months.

"The fact (that) North Korea has almost normalised ICBM tests over the last year is a concern," Joseph Dempsey, a researcher at the International Institute for Strategic Studies, told AFP.

Soo Kim, a former CIA Korea analyst, said that Kim's regime "has essentially desensitised the international community to its weapons tests," she told AFP.

"We've reached a point where an ICBM test draws no greater attention than a short-range missile test," she said.

"We'll continue to see North Korea advancing and expanding its suite of weapons capabilities in the days to come."
