On Sunday, Daily Signal correspondent Nolan Peterson tweeted that this was "the most risky moment" he had seen in Ukraine "in years".
Moscow is able to control access between the Sea of Azov and the Black Sea after it built a bridge that straddles the Kerch Strait between Crimea and southern Russian Federation. Reviving the patriotic fervor that accompanied Putin's annexation of Crimea in 2014 could help him offset growing domestic discontent over the economy and changes to Russia's pension system.
However, after its seizure of Crimea, Russia built a almost 12-mile bridge spanning the strait.
In a phone call with Poroshenko, NATO Secretary General Jens Stoltenberg offered the alliance's "full support for Ukraine's territorial integrity and sovereignty". An extraordinary meeting of NATO-Ukraine ambassadors is planned in Brussels later Monday.
Minister of Foreign Affairs Sven Mikser (SDE) also condemned Russia's actions.
On Monday, Kremlin spokesman Dmitry Peskov described the incident as a "dangerous provocation" by Kiev that required "special attention and special investigation", the state news agency TASS reported.
Ukraine is facing a presidential election next year and Russian Federation has historically manipulated Ukrainian elections and has also fomented a violent uprising in eastern Ukraine.
A bilateral treaty gives both countries the right to use the sea, which lies between them and is linked by the narrow Kerch Strait to the Black Sea. Russia's FSB security service said the ships - two small Ukrainian amoured artillery vessels and a tug boat - had illegally entered its territorial waters.
Since last April the Russian navy has also subjected to inspections over 150 ships going to and from the Ukrainian ports. The three wounded sailors were not in a serious condition and were recovering in hospital.
The Ukrainian vessels apparently wanted to travel through the strait to other ports in Ukraine.
The emergency session was called after Russian warships fired on Ukrainian vessels in the Kerch Strait, injuring six servicemen.
It also accused the Ukrainian government of coordinating the actions with the USA and the European Union.
For now, while Polygraph.info finds that Russian council member's proclamations on the potential of martial law in Ukraine are consistent with the context of the country's basic law, the extent to which it will be used and its implications appear to be limited and so the final effects are unclear.
It's unclear how Avakov obtained the video.
Ian Brzezinksi, an expert on Russian and resident senior fellow at the Atlantic Council think tank, called Sunday's incident a "brazen" attempt by Putin to choke off Ukraine and regain control of former Soviet Union territory. However, it has since been reopened for civilian ships, according to TASS.
Parliament voted overwhelmingly for the motion following a five-hour debate. "I think we should also consider the message itself to Ukraine and free world itself. And this aggression has already led to consequences".
With Ukraine's finances under pressure from looming foreign-debt payments on stress on other emerging markets, there was concern that martial law could obstruct global aid payments.
