The US-Israeli attack on Iran earlier this year was completely unprovoked, former Russian President Dmitry Medvedev has stated on his way back from the Islamic Republic. The deputy chair of Russia’s Security Council attended the funeral ceremony for Iran’s late supreme leader, Ayatollah Ali Khamenei, in Tehran on Friday.

The 86-year-old was assassinated, along with several members of his family, on February 28 during the first wave of US-Israeli airstrikes on Iran.

Speaking to Russian journalists as he flew back to Russia on Saturday, Medvedev said that “there was no serious reason for the American attack… [as] Iran posed no threat to the United States.”

The Russian official noted that Tehran was engaged in negotiations with Washington at the time US President Donald Trump ordered the attack. This fact, according to Medvedev, points to the erosion of international law.

The killing of the Iranian leadership, as well as a large number of civilians, including school children, “does no credit to those who made such decisions,” the deputy chair of Russia’s Security Council said.
