Dmitry Medvedev, the deputy chairman of Russia's Security Council, said on Sunday that US President Donald Trump had started a new war for the US by attacking Iran. US forces struck Iran's three main nuclear sites, Trump said late on Saturday, and he warned Tehran it would face more devastating attacks if it does not agree to peace.

"Trump, who came in as a peacemaker president, has started a new war for the US," Medvedev wrote on his Telegram channel, adding that "with this kind of success, Trump won't win the Nobel Peace Prize".

The leader of Russia's Liberal Democratic Party (LDPR), Leonid Slutsky, said the strikes "had no military reason for the US and cannot be justified under international law". "The consequences of the escalation threaten to go beyond the region. Washington understands the inevitability of Tehran's response. All this brings the spiral of confrontation to a new level and increases the risks of World War III," said Slutsky, who heads the State Duma international affairs committee.

Iran Confirms Sites Hit, IAEA Reports Minimal Damage

Following the US strikes, the Atomic Energy Organisation of Iran confirmed that attacks took place on its Fordow, Isfahan, and Natanz sites. Criticising the US President’s decision to strike Iran, Medvedev said that Donald Trump, who came as a peacemaker president, has started a new war for the US. The remarks from the Russian politician came after the International Atomic Energy Agency (IAEA) reported that the Fordow Fuel Enrichment Plant suffered minimal damage in the US airstrikes, as claimed by multiple agencies.

“A number of countries are ready to directly supply Iran with their own nuclear warheads," said Medvedev in an X post, adding that the US attacks on three Iranian nuclear sites led to the opposite result from what President Donald Trump had set out to achieve.
