KYIV, July 5 – All European countries must unite in opposing the construction of the Russian main gas pipeline Nord Stream 2 under the Baltic Sea as a threat to their own energy security, President of Ukraine Volodymyr Zelensky has said.

"We should continue to oppose the implementation of the project [Nord Stream 2] and involve all partners in this difficult struggle. Not only Ukraine. Entire Europe should unite to counter this energy threat," Zelensky said during a speech at the Ukraine 30. International Relations forum in Kyiv on Monday.
