A number of arrests have been made in Balcombe, West Sussex, where energy firm Cuadrilla had been drilling for oil. Protesters had chained themselves together and blocked access to the site.
Anti-fracking campaigners also blockaded Cuadrilla's headquarters in Staffordshire.
In London, protesters super-glued themselves to the London office of the energy firm's PR company, Bell Pottinger.
