Russia-Ukraine tensions rise after Kerch Strait ship capture
Ukraine's parliament is to decide whether to bring in martial law, after the capture of three of its naval vessels by Russia, BBC informed.
The three ships were sailing off the coast of Crimea, which was annexed by Russia in 2014, when they were seized.
Ukraine said Russia rammed one of its boats in an "act of aggression", while Russia said the ships had illegally entered its waters.
The incident marks a major escalation of tension between the two countries.
This is the first time the two militaries have come into open conflict in recent years, although Ukrainian forces have been fighting Russian-backed separatists in the east of the country.
The captured crew members are now being questioned in Kerch, Russia says.
