reported by activists in Russia:

"An ELF group claims responsibility for torching of a workers' shed (the building was checked to ensure it was unoccupied prior to the attack) at a treecut site in southern Moscow (Bitcevski forest) on the night of april the 11th. An 5 liters of gasoline and incendiary device for time delay were used because of close proximity to guardhouse and serious sentry presence in the region. The forest has seen numerous ecotage actions (spiking, torchings of vehicles and storage sheds, etc), hence intense police attention. No photos or videos were released. The shed and its contents exploded 5 minutes later for unknown reasons.
