A seventh wave of mobilization of troops can be declared in case fighting escalates in the east of Ukraine, but there are no grounds for such a decision yet, according to Ukraine's presidential adviser Yuriy Biryukov.
'The seventh wave of mobilization will be declared if the situation at the front worsens,' he stated, Unian reports.
'If this happens, the mobilization will primarily concern reserve military troops, who have already fought in Donbass. They will stand faster in the ranks of the defenders at the front and will not require long training,' he added.
Biryukov, however, said there was no radical exacerbation at the front, currently. 'As of today, we have not witnessed increased tension,' he noted.
