Martial law declared in parts of Ukraine has ended after 30 days, amid continuing tensions with Russia in the Kerch Strait, BBC reported.

The measure was in force in 10 regions along the Black Sea and the borders with Russia, Belarus and Moldova.

It was declared after the capture of three Ukrainian naval vessels and 24 sailors by Russian forces in November.

During the emergency, Ukrainian armed forces were put on combat readiness and reservists were called up.
