BRUSSELS (Reuters) - NATO members on Tuesday reaffirmed their support for Ukraine during talks with the country's officials held in response to Russia's launch of an experimental intermediate-range ballistic missile last week.

Putin said the missile attack was in response to Ukraine firing weapons supplied by the United States and Britain into Russia.

The new ballistic missile fired by Russia struck a military-industrial facility in the central Ukrainian city of Dnipro, but its real mission was delivering a deadly new message to NATO.

"For the Republic of Korea, these actions pose a serious threat, as North Korean troops are gaining combat experience, which could present additional security challenges in the region in the future," Defense Minister Rustem Umerov said following his visit to South Korea.

North Korean leader Kim Jong-un has visited the facility several times and the state media has previously talked about the tactile missiles being mass-produced at the location.
