Leftwing militants claim responsibility for arson attack on Berlin power grid

German leftwing militants from the Vulkangruppe have claimed responsibility for an arson attack on a bridge in Berlin that has cut power to tens of thousands of homes and businesses. The group, protesting over the climate crisis and AI, targeted high-voltage cables near a heat and power station, affecting up to 35,000 homes and 1,900 businesses. The attack, which the group described as an 'act of self-defense and international solidarity,' has caused significant disruptions, including interruptions to mobile networks and commuter lines, and has left some residents without heat and hot water. The group apologized for the impact on less well-off residents but expressed limited sympathy for the 'ruling class' affected by the power cut.
