Heated exchanges erupted at the UN Security Council as Russia accused the West of a cover-up over the Nord Stream pipeline blasts. Moscow's Dmitry Polyansky slammed Germany for hiding evidence from its own people and mocked Denmark's closed investigation, declaring: "We're not discussing LEGO." The US tried to shift attention to the war in Ukraine, while China demanded an impartial probe. Denmark defended Berlin's investigation, and Algeria warned of global security risks from such attacks. The case took a new twist after Italy arrested a Ukrainian national linked to the 2022 sabotage, as Moscow reiterated that the blasts were state-backed and pointed to Washington's suspected role.
