According to the Eastern American Diocese website, His Eminence Metropolitan Hilarion of Eastern America and New York issued instructions for prayers for peace in Belarus in the churches of the diocese:
Having observed with grief and great concern the political upheavals in the Republic of Belarus, we ask that the faithful of the Russian Church Abroad strengthen their prayers for peace and the restoration of lawfulness among our brothers and sisters in that country.
Rectors of the parishes and monasteries of the Eastern American Diocese are instructed to add this special petition to the Augmented Litany at the divine services this Saturday the 29th and Sunday the 30th of August.
The prayer for peace in Belarus in English:
O Master, Lover of mankind, King of the ages and Bestower of good things, Who didst destroy the middle wall of enmity and grant peace to the human race: do Thou now also send down peace into the hearts of the people of Belarus; instill in all the fear of Thee and confirm in them longsuffering and love one for another; extinguish every dispute and banish all temptation to disagreement, we pray Thee, quickly hearken and graciously have mercy.
