the Ukrainian vessels were sailing between two Ukrainian ports: from Odessa in the Black Sea to Mariupol in the Azov Sea. The only waterway that connects these is the Kerch Strait between Crimea and mainland Russia. Kiev says it notified Moscow in advance that its navy ships would be sailing through the area. Moscow denies that it was given warning.
While both Russia and Ukraine have freedom of navigation in the Kerch Strait under a 2003 treaty, there are detailed technical rules on how vessels should pass through the narrow, complex waterway. All traffic in the area is controlled by the Crimean sea port of Kerch, and every ship should contact the facility, report her route and destination, and receive permission to sail through the Strait.
krainian vessels continued their journey despite warnings from the Russian authorities. The Ukrainian Navy said the military vessels were sailing from the port city of Odessa to the Azov port of Mariupol as part of a scheduled routine transfer and claimed that it warned the Russian authorities about the trip in advance.
The FSB denounced the actions of the Ukrainian vessels as "provocation." A video released by Russian authorities shows the Ukrainian vessels maneuvering in close proximity to the Russian ones.
At midnight, the FSB released a statement, saying that Russian warships had to open fire after the three Ukrainian ships ignored "legal demands to stop" and continued "performing dangerous maneuvers."
Three Ukrainian sailors were wounded and given medical assistance, while the ships were seized. The group of ships that were heading to the strait from the Azov Sea turned back to their port.
round midnight, Ukrainian President Petro Poroshenko instructed the National Security and Defense Council of Ukraine (NSDC) to convene for an emergency meeting proposing to impose martial law. The council has moved forward with the motion. The Verkhovna Rada, the Ukrainian parliament, will vote on whether to approve the decision in an extraordinary session on Monday.
Poroshenko stated that martial law will not mean immediate mobilization of troops and said that no offensive operations are being planned.
