The ties between Russia and Hamas are well documented: (from wikipedia cuz I'm lazy)
During the 2023 Israel–Hamas war, Russia condemned both the initial Hamas attack and Israel's response. Russia maintained relations with both parties and presented itself as a potential mediator.
After the 7 October Hamas attack on Israel, which initiated the war, Russia condemned the attack as "terrorism". Putin sent condolences to the families of the killed Israelis and said Israel had a right to defend itself, describing the Hamas attack as "unprecedented in its cruelty". He also condemned the subsequent Israeli bombardments of Gaza and called for a two-state solution to resolve the conflict. Russian UN diplomats later condemned both the Hamas attack on Israel and Israeli shelling of civilian neighborhoods in Gaza. However, Russia voted against a resolution condemning Hamas at the United Nations General Assembly.
Some commentators said that Russia has grown closer to Hamas and more hostile to Israel. According to The New York Times, Russian state media and leading social networking platforms spread support for Hamas and denigrated Israel and its main ally, the U.S. Putin has said that the war shows "a clear example of the failure of U.S. policy in the Middle East". On 14 October, Hamas thanked Putin for his "position regarding the ongoing Zionist aggression against our people." On 26 October, Moscow hosted a Hamas political delegation, led by Mousa Abu Marzook, which Israel condemned as "a reprehensible step that gives support to terrorism and legitimacy to the horrific acts of Hamas terrorists." Amid the war's hostage crisis, Hamas released kidnapped Russian-Israeli dual nationals. Hamas described these actions as a gesture of appreciation for Russia's support for the Palestinian cause.
In December 2023, Russia's Foreign Minister Sergey Lavrov said that Israel's stated goals in its invasion of Gaza were similar to Russia's stated goals in its invasion of Ukraine.
