Russian President Vladimir Putin, while commenting on the naval incident that led to the detention of Ukrainian ships in the Kerch Strait, noted the attempt to breach the maritime border was a provocation prepared in advance as a pretext to introduce martial law in Ukraine.
"Today, the United States and Allies conducted an extraordinary flight under the Open Skies Treaty", the Pentagon release said. "The timing of this flight is intended to reaffirm US commitment to Ukraine and other partner nations".
The United States stated earlier that it supports Kiev in the naval incident in the Kerch Strait, when three Ukranian ships ignored Russian Border Guards while trying to enter the region. Following their detention by the Russian authorities, Ukranian President Petro Poroshenko introduced martial law in all regions bordering Russia as well as the coasts of the Black Sea and the Sea of Azov.
