MOSCOW, October 3. /TASS/. The State Duma, the lower house of Russia’s parliament, is ready to discuss as a matter of priority the suspension of the plutonium disposal deal with the United States, lawmaker Leonid Slutsky said on Monday.

"The issue is extremely important. The talk is about the need to take urgent measures to protect Russia’s security," he said. 

"As soon as the relevant documents are submitted to the State Duma, we’re ready to consider them as a matter of priority," the lawmaker said, adding that "this will possibly take place in the imminent future."

Russian President Vladimir Putin ordered earlier on Monday the suspension of the plutonium disposal agreement with the United States over Washington’s unfriendly actions towards Russia.
