On February 9th, the Donetsk republic authorities announced that the regime in Kiev was behind the assassination of Mikhail Sergeyevich Tolstykh, nom de guerre Givi. They also claim that  they know who were individuals, involved in this crime.

Igor Mosiychuk, a Rada deputy representing the “Radical party,” an ultra-radical nationalist known for his alleged involvement in intimidation of the fellow members of the parliament, kidnapping and other criminal activities.
In his interview to the local TV channel, Igor Mosiychuk says that he knows that Motorola was “liquidated” by Ukraine, and not by the Russian Federation, FSB or some kind of Donets insider job, as some claimed.
“It’s our people that liquidated Motorola. I cannot say anything about Givi yet, but I can say about Motorola and who did him in. I can confirm that Motorola was liquidated with the help of our armed forces and it was done by our people who live in Donetsk.”
“Mossad kills around the world, and everyone knows that Mossad does the killing and everyone is afraid to do something against the state of Israel, like what Givi and Motorola did against the state of Ukraine.”
“I am certain that the next will be Zaharchenko.” “I am saying what I am allowed to say.”

I should translate everything that a Rada deputy Igor Mosiychuk says in his interview posted above, but I am having a mental fatigue, listening to him.
During his interview, he mentions Israel, Knesset and Mossad several times as an example of political and military strategy.  This should give you an understanding  who are writing guidelines for Poroshenko’s government.
