Board member of the Vostok [East] SOS charity foundation, coordinator of the Humanitarian Policy Development Office of Ukraine Oleksandra Dvoretska said the Ukrainians had been detained because Reutski had been filming the arrest of a passer-by by law enforcers on his mobile phone. In turn, Belarus' Ministry of Foreign Affairs said the Ukrainians had been detained as they were working in that country without accreditation. However, Dvoretska emphasized Vasylyev and Reutski had been in Belarus legally, and there were no questions from the border guards when crossing the border.
Meanwhile, Ukrainian Foreign Minister Dmytro Kuleba says the two men are at the Embassy of Ukraine in Belarus now, being under the protection of Ukrainian diplomats.
Earlier, Ukrainian Deputy Foreign Minister Yevhen Yenin said one of the Ukrainians detained during recent protests in Belarus would be released on August 14 after paying a fine.
