In June 2010, Greenpeace anti-nuclear activists invaded Forsmark nuclear power plant to protest the then-plan to remove the government prohibition on building new nuclear power plants. In October 2012, 20 Greenpeace activists scaled the outer perimeter fence of the Ringhals nuclear plant, and there was also an incursion of 50 activists at the Forsmark plant. Greenpeace said that its non-violent actions were protests against the continuing operation of these reactors, which it says are unsafe in European stress tests, and to emphasise that stress tests did nothing to prepare against threats from outside the plant. A report by the Swedish nuclear regulator said that "the current overall level of protection against sabotage is insufficient". Although Swedish nuclear power plants have security guards, the police are responsible for emergency response. The report criticised the level of cooperation between nuclear site staff and police in the case of sabotage or attack.
