Poltorak said mobilization will depend on the situation in the eastern part of the country, where Ukrainian army is fighting against Donbass independence supporters.
"Tomorrow I will have a meeting in Uzhhorod [the city in Ukraine's Zakarpattia Region] on the issue of the fifth wave of mobilization…" Poltorak said, as cited by Gazeta.ru.
Previously it was reported that Ukraine's Defense Ministry had trouble recruiting soldiers. Over 10,000 cases of desertion have been registered in the Ukrainian Army since the outbreak of the Donbass War in April 2014.
Ukrainian parliament Verkhovna Rada has announced six waves of mobilization so far. By the end of 2014 the strength of Ukrainian Armed Forces grew from 130,000 to 232,000.
Ukrainians have been protesting against the mobilization. They travel to work abroad or simply reside at their relatives' in other countries. Almost 1.3 million Ukrainian draftees live in Russia.
