Ukrainian President Volodymyr Zelensky has called an emergency meeting of top security and defense officials for Friday, his spokesperson said on Thursday.
Serhiy Nykyforov announced the meeting on Facebook after the Kremlin said Russian President Vladimir Putin would sign formal documents on Friday proclaiming Moscow's annexation of four Ukrainian regions following what Kyiv called sham referendums organized by Russia at gunpoint.
"President Volodymyr Zelensky has called an urgent meeting of the National Security and Defense Council of Ukraine for tomorrow. The agenda and other details will be announced later," Nykyforov said.
