Two men serving time for murder married last week in a French prison at Poissy, near Paris.

Alfredo Stranieri, 56, and Germain Gaiffe, 45, were married by Poissy Mayor Frederik Bernard. Their union was witnessed by notorious terrorist Illich Ramirez Sanchez, known as Carlos the Jackal, who is serving two life sentences and controversial comedian Dieudonne M'bala, known simply as Dieudonne.

Stranieri, who targeted his victims through classified ads, was dubbed the “small ads killer” by the media. Gaiffe is serving a 30-year sentence for beheading a man.

Critics, however, have called the wedding a publicity stunt.

Citing Dieudonne's well-known opposition to gay nuptials, La Nouvel Observateur called the marriage “a sham” orchestrated in “bad taste” by Dieudonne, who had previously called the marriage law a “Zionist project that aims to divide people.”

“The marriage law for all opened the door to anything big,” Dieudonne told the AFP. He added that the newlyweds were looking to adopt an inmate.

Dieudonne attempted to attend the wedding wearing a white dress. When asked to change out of the dress, he reportedly responded: “This is the France of tomorrow.”
