U.S. Ambassador to the United Nations Nikki Haley warned Russia on Monday that its seizure of three Ukrainian vessels was an "outrageous violation of sovereign Ukrainian territory" and urged Moscow to reduce tensions caused by its "arrogant" act.
Haley said she spoke with President Donald Trump and Secretary of State Mike Pompeo earlier on Monday and her statement "reflects the concerns at the highest level."
"As President Trump has said many times, the United States would welcome a normal relationship with Russia. But outlaw actions like this one continue to make that impossible," said Haley, a member of Trump's Cabinet.
