George Clooney says photographers who captured images of him and his wife, human rights lawyer Amal Clooney, cradling their newborn twins will be “prosecuted to the fullest extent of the law.”

The pictures published by French magazine Voici were taken at the Clooneys’ residence in the Lombardy region of Italy. The magazine claims the photos are the first to be made public of twins Ella and Alexander, who were born June 6.

The actor says the photographers “scaled our fence, climbed our tree and illegally took pictures of our infants inside our home.”

He adds that the photographers, the photo agency and the magazine will face prosecution because the safety of the couple’s children “demands it.”
