The three countries also urged North Korea "to take concrete steps toward its complete, verifiable and irreversible denuclearization" and said international sanctions should remain in place and be fully enforced until its nuclear and ballistic missile programs are dismantled.
The UK, France and Germany issued a joint statement to reporters after a closed Security Council briefing by U.N. political chief Rosemary DiCarlo and consultations. The council did not issue any statement.
Russia's deputy U.N. ambassador Dmitry Polyansky told reporters before the meeting that "we still have very little information. Was it a ballistic missile or not ballistic missile? What was the launch? How many were launched?"
He said Russia tries to base its position "on trustworthy sources" and "I don't think we should rush to any conclusions to this." North Korea said Thursday its leader Kim Jong Un supervised the first test firing of a new multiple rocket launcher system that could potentially enhance its ability to strike targets in South Korea and U.S. military bases there.
The report by the official Korean Central News Agency differed from the assessment by South Korea's military, which had concluded Wednesday's launches were of two short-range ballistic missiles. Earlier Thursday, U.S. Secretary of State Mike Pompeo said in Thailand that the Trump administration remains ready to resume talks with North Korea now. President Donald Trump and Kim Jong Un agreed to a meeting during talks late last month in the Demilitarized Zone between the two Koreas.
Under U.N. sanctions, North Korea is barred from using ballistic missiles. The United Kingdom, France and Germany said "it is vital that the Security Council shows unity in upholding its resolutions."
They also said that "serious efforts by North Korea to re-engage diplomatically and make progress on denuclearization are the best way to guarantee security and stability on the Korean Peninsula, as well as a brighter future for the people of North Korea."
"Ultimately it is the North Korean regime that is responsible for the dire situation of its people," the UK, France and Germany said.
