“The authorized Ukrainian government authorities did not receive official information about the grounds for the detention, personal data and the procedural status of these citizens,” she wrote on Facebook.

She turned to Moskalkova "with a request to provide official information about the detained citizens."

“Namely: personal data, the grounds for the detention and their procedural status,” the Ombudsman said.

Earlier, the FSB announced the detention of two residents of Kerch in 2003 and 2004, who were preparing terrorist attacks in two educational institutions in the Crimea.

According to the agency, they are followers of Vladislav Roslyakov, who shot at the Kerch college in the fall of 2018.

The head of the IC, Alexander Bastrykin, ordered to carry out investigative actions in this case.
