Israel believes all means must be used to stop Iran's nuclear program, Israeli Ambassador to Russia Dorit Golender said here Thursday.

Golender told a press conference that Iran's Wednesday statement and the country's nuclear activities "shows that Tehran tries to use research for peaceful uses as a cover for what it does within its military program."

However, the ambassador also stressed that Israel is trying to solve all problems through peaceful means.

Earlier on Thursday, Iranian Ambassador to Moscow Mahmoud Reza Sajjadi said here that Teheran would not suspend its building of centrifuges, but was ready for talks with the six international mediators, including the U.S., China, Russia, Britain, France and Germany.

Iranian President Mahmoud Ahmadinejad on Wednesday unveiled nuclear fuel rods, a new generation of centrifuges and a number of radioactive medicines for the treatment of cancer.

The tension between Iran and Western powers and their close ally Israel was simmering, as they accuse Iran of pursuing nuclear weapons through its nuclear program, a charge categorically rejected by Tehran.
