The Ukrainian parliament approved the martial law decision after the tension rose between Russia and Ukraine.

Responding to the clash, between the Ukrainian navy and Russia's coastguard, Ukraine imposed martial law on Monday for 30 days in parts of the country most vulnerable to an attack from Russia after President Petro Poroshenko warned of the "extremely serious" threat of a land invasion.

On the other hand, Russia denounced the martial law declared in Ukraine.

"The imposition of martial law in some regions may pose a risk of escalating tensions in the conflict-hit region, namely the south-east," Kremlin spokesperson Dmitry Peskov said Tuesday.
