Strikes on Iran's nuclear sites may force it to develop nuclear weapons and trigger more risks to the non-proliferation regime, Russia's Foreign Minister Sergei Lavrov said Tuesday.

"Scientists in nearly all countries....are convinced that strikes may slow down the Iranian nuclear program. But they will never cancel it, close it down or eliminate it," Lavrov said in an interview with the radio Kommersant FM.

He warned that Iran may have no option but to develop nuclear weapons in response to the strikes.

"Even the CIA and other US agencies admit now there is no information to confirm the political decision of the Iranian administration to produce nuclear weapons. I am almost confident that such a decision will be made after strikes on Iran," Lavrov said.

"Actually, this aggressiveness creates more risks to the non-proliferation regime than strengthens it," he said.

Russia has called for the resumption of negotiations between Iran and major mediators including Russia, US, France, Britain, China and Germany.
