MOSCOW, April 26. /TASS/. The shelling of the State Security Ministry in the unrecognized Transdniestria has been incontrovertibly traced to Ukraine, a government source told TASS on Tuesday.

"According to law enforcement agencies of the Transdniestrian Moldovan Republic, the building of the State Security Ministry of the TMR in Tiraspol came under mortar fire at 17:44 on April 25," the source said. "Out of three shots, one hit the window on the second floor. There are no casualties. The building has sustained damage."

The source said the attack was perpetrated by three as yet unidentified people who came in from the territory of Ukraine, bypassing checkpoints near the Novovladimirovka settlement 8 kilometers north of Tiraspol at 17:15 and then left for Ukraine using the same route at about 18:00.

The source also said two explosions took place at an aircraft parking site of the Transdniestria’s Defense Ministry, which is adjacent to the Tiraspol Airport, at about 11 pm on April 25. No casualties or damage were reported.

On April 26, blasts damaged radio towers at the Transdniestria Ratiotelecenter company (owned by the Russian state enterprise called the Russian Television and Radiobroadcasting Network) at 6:50 am. No casualties were reported.

"The traces of the shelling of the Transdniestrian State Security Ministry incontrovertibly lead to Ukraine," the source said. "The other two terrorist attacks are a logical extension of that one.".
