Moscow, Jan 23 (IANS): Ukrainian forces are storing Western-supplied missiles and artillery shells in nuclear power plants, Russian Foreign Intelligence Service Director Sergey Naryshkin said on Monday, reports said.

He claimed that Kiev has been using the plants as cover for ammunition stockpiles, RT reported.

"There is credible information that Ukrainian troops are stockpiling the Western-supplied weapons and ammunition on the territory of nuclear power plants," Naryshkin said, according to a statement on the intelligence service's website.

He added that the armaments include rockets for US-made HIMARS launchers and missiles used by foreign air defence systems, as well as "large-caliber artillery shells".

According to Naryshkin, several cars loaded with "lethal cargo" were delivered by rail to the Rovno Nuclear Power Plant in western Ukraine during the last week of December alone. "They rely on the calculation that the Russian Armed Forces would not strike nuclear power plants because they realise the danger of a nuclear disaster," the intelligence chief said, RT reported.

Russia has accused Ukrainian forces of shelling the Zaporozhye Nuclear Power Plant, which is Europe's largest. It is located in the eponymous region which, along with three other former Ukrainian territories, joined Russia following referendums in September.

Kiev denied targeting the facility and claimed that Russia was using the plant as a base and cover for its soldiers. Russian officials said that heavy weapons have never been deployed to the site, and that a select number of armed security personnel were maintaining the safety of the plant, as it is located near the frontline, RT reported.
