Here’s a marriage made in hell.

A British schoolgirl, who ran away from home to join ISIS, tied the knot with an Australian extremist dubbed the “Ginger Jihadist” because of his telegenic red hair, according to a published report on Sunday.

The unholy union between Amira Abase, 16, and Abdullah Elmir, 18, was confirmed in a text message from the bloodthirsty groom himself, The Sunday Mail in London said.

The red-headed Elmir has been a favorite ISIS propaganda tool since he ran away from his Sydney home last year.

In his latest message, Elmir said ISIS is “itching to do an attack” on London and won’t relent until “the black [ISIS] flag is flying over Buckingham Palace.”

The child bride Abase was only 15 when she and two other East London pals ran away to Syria, via Turkey, last year.
