"It is reported that immediately after your appeal on behalf of the Russian Union of Journalists, as well as requests of the OSCE representatives, the International Federation of Journalists (IFJ) and other international organizations in connection with the arrest of Ukrinform correspondent Roman Sushchenko, the Russian Union of Journalists held an emergency working meeting, where it was decided to appeal to the leadership of the FSB for explanations," Secretary of the Russian Union of Journalists Nadezhda Azhgikhina wrote in a letter to the National Union of Journalists of Ukraine, reported.

According to Azhgikhina, the organization is "extremely concerned about what happened" and continues to monitor the situation.

The head of the National Union of Journalists of Ukraine Sergiy Tomilenko has confirmed that once the Union became aware of the detention of Ukrainian journalist in Moscow, it asked the Russian Union of Journalists, the International and European Federation of Journalists, and the OSCE Representative on Freedom of the Media Dunja Mijatovic to show solidarity in campaigning for the release of the Ukrainian journalist.

"The absurdity of espionage charges against Roman Sushchenko is quite obvious. But this obviousness should be stressed not only in statements but also in the appeals of various international structures," Tomilenko said.
