MOSCOW, May 28. /TASS/. Nationalists intend to open fire on Russian territory and blow up chemical tanks in the city of Sumy in order to pin the blame for a chemical weapons attack on Russia, Colonel-General Mikhail Mizintsev, chief of Russia’s National Defense Management Center, said on Saturday.

"According to the intelligence received from captured Ukrainian soldiers, the militants of nationalist battalions are preparing another provocation with hazardous chemicals in the city of Sumy," said Mizintsev, who heads the Russian Joint Coordination Headquarters in Ukraine.

Mizintsev pointed out that "neo-Nazis have plans to shell the border areas of the Russian Federation from the city’s (Sumy - TASS) residential area to trigger Russian units to return fire, and then they will blow up tanks with hazardous chemicals."

"The Kiev authorities are going to use this cynical action to blame the Russian armed forces for the alleged use of chemical weapons and for indiscriminate strikes against civilians," the top brass said.

According to Mizintsev, foreign reporters are in Sumy for photo and video shooting.
