Add animal rights activists to the ever-growing list of ISIS haters — following reports that the fiends had weaponized a pair of cows by turning them into explosives-laden booby traps that killed a civilian.

The bovines were strapped with explosive belts and were headed toward a military checkpoint in Diyala province when Iraqi soldiers opened fire and “blew them up,” killing a bystander, according to a report on the Kurdish language Rudaw news website, the Independent reported.

A local official, Sadiq Husseini, told the Kurdish outlet that the incident “shows that the group has lost the ability to recruit young people and would-be suicide bombers, instead they are using cattle.”

Diyala province is home to Kurds, Sunnis and Shias and is at the heart of a dispute between the Kurdistan Regional Government and Iraq, with both claiming ownership, Fox News reported.

ISIS has taken advantage of the dispute and worked to re-establish itself after losing most of the territory it had held under its so-called caliphate.

ISIS holds a “durable support zone” and has “increased its attack tempo against security forces, local tribal figures and commercial sites,” according to the Institute for the Study of War.

Terrorists have used animals to carry out their cowardly attacks in the past.

In November 2003, more than a dozen rockets were fired from donkey carts that slammed into Iraq’s Oil Ministry and a pair of Baghdad hotels.

Other rocket launchers mounted on donkey carts were found in Waziriya, a neighborhood north of downtown, and in all, weaponized donkeys have killed 14 people.
