MOSCOW. March 14 (Interfax) - Russian Communist party leader Gennady Zyuganov has blamed the United States for the spread of avian influenza, or bird flu, in a number of European countries, including Russia.

"The forms of warfare are changing. It's strange that not a single duck has yet died in America - they are all dying in Russia and European countries. This makes one seriously wonder why," Zyuganov said at a press conference at the Interfax main office on Tuesday.

Zyuganov said that he has good knowledge of war gases as he dealt with them during his army service.

"I tested all kinds of war gases at a range myself," he said.

Asked to be more precise as to whether he believes the bird flu outbreak could be a deliberate attack by the U.S., Zyuganov answered positively.

"I not only suggest this, I know very well how this can be arranged. There is nothing strange here," he said.
