The Russian Orthodox Church has called on international leaders to "protect" its followers in Ukraine in the face of what it called official pressure on Moscow-appointed clerics.

In a statement issued on December 14, the Russian Orthodox Church said Patriarch Kirill has sent a letter to the UN Secretary-General Antonio Guterres, Thomas Greminger, the secretary-general of the Organization for Security and Cooperation in Europe (OSCE), German Chancellor Angela Merkel, French President Emmanuel Macron, Pope Francis, and other spiritual leaders, urging them to help protect believers and their faith in Ukraine, Radio Free Europe / Radio Liberty said.

"The interference by the leaders of the secular Ukrainian state in church affairs has recently assumed the shape of undue pressure being exerted on the bishops and priests of the Ukrainian Orthodox Church, which can be defined as the start of all-out persecution," Patriarch Kirill was quoted as saying in the statement.

The statement was issued a day before a meeting on December 15 of senior figures from Orthodox Christian communities in Ukraine in Kyiv in a bid to form a new, unified, independent Ukrainian Orthodox Church and elect a leader, known as a Primate.

The meeting could be a crucial step in years of efforts to create a church in Ukraine that is independent of Moscow.

The Ukrainian Orthodox Church of the Kyiv Patriarchate said on December 13 that Ecumenical Patriarch Bartholomew of Constantinople, the "first among equals" in the global Eastern Orthodox faith, will hand over a "tomos" –  a decree granting autocephaly, or independence –  to the future head of the local Orthodox Church in Ukraine on January 6.

Ukraine currently has three main Orthodox denominations: the Ukrainian Orthodox Church of the Moscow Patriarchate, which remained subordinate to Russia after the breakup of the Soviet Union, and two breakaway entities – the Ukrainian Orthodox Church of the Kyiv Patriarchate and the Ukrainian Autocephalous Orthodox Church.

Bartholomew announced the decision to recognize Ukraine's request for an autocephalous church in October.
