Tehran, November 10 (KCNA) -- Iran's high cleric Seyyed Mahmoud Alavi on Nov. 6 warned the U.S. and Israel against their attempt at military attack on Iran.

They have to pay a heavy price for any military attack on Iran's nuclear facilities, Alavi was quoted as saying.

They are aware of the fact that putting their anti-Iran threats into practice would cost them dearly, and thus they would not become involved in such "folly," he said.
