"[I] spoke to President Poroshenko. We have a similar assessment of the situation in Crimea and Donbas. Russian version of events [is] unreliable," Tusk tweeted on Wednesday. On August 10, the Russian Federal Security Service (FSB) said terrorist acts allegedly plotted by the Ukrainian intelligence had been averted in Crimea. It was reported that the Russian special services, with support from other defense and security units, had prevented groups of saboteurs and terrorists from breaking into Crimea from the territory of Ukraine. The Russian side claimed that one Russian serviceman and one FSB officer were killed and reported that nine people involved in the events had been detained. Two of them were arrested. The Ukrainian Defense Ministry, the Main Intelligence Department and the National Security and Defense Council denied the reports on Ukrainian saboteurs. The Defense Ministry also said the accusations made by Russia of attacks on the peninsula from mainland Ukraine were similarly groundless.
