THE evil priest slayers are seen making an oath of hatred in a vile video released by IS last night.

Adel Kermiche and his accomplice — named by police sources yesterday as Abdel Malik Petitjean — pledge their allegiance to the terror group.

The footage emerged as Kermiche, 19, was exposed as a philanderer who married four times just to have sex — then dumped all his partners within a few days.

It was also revealed the fanatics held two nuns as human shields after slitting 85-year-old priest Jacques Hamel’s throat in a Catholic church in France.

And foreign intelligence agents reportedly warned French spooks of an ­imminent attack four days before the atrocity in Saint-Etienne-du-Rouvray, Normandy, on Tuesday.

A photo of Petitjean, also 19, was said to have been circulated but police could not identify him in time to prevent the horror.

The knife killers were shot dead by cops after an hour-long siege at the church, during which a pensioner worshipper was stabbed.

Kermiche, in a camouflage jacket, and his accomplice with a red shawl-like cloth over his head and shoulders are thought to have been filmed by IS hours before storming the church and taking hostages.

They describe themselves under assumed names Bin Omar and Abu Gayed El Hanafy.

Separate dramatic footage emerged yesterday of a nun fleeing to safety before heavily-armed cops open fire on the ­cowardly killers.

Teenage pals of womaniser Kermiche claimed he repeatedly got married and then swiftly got divorced to bypass Islamic prohibitions on extra-marital sex. One said: “He only did it for sex.”

Kermiche reportedly told one woman on social media: “I want to get married before Ramadan.”

She replied: “Send me a photo.” But he refused, saying: “No, the sages of Islam forbid it.”

A former schoolmate, named only as Bodri, 22, said Kermiche fancied himself as a looker and liked to flirt with girls. He added: “He wanted to be a model.”

Snaps of a younger Kermiche show him wearing a T-shirt with the slogan “I know HTML (How to meet ladies)”.

Francis Da Silva, 35, who manages a supermarket near Kermiche’s home, said the teen “partied and bought alcohol”.

Wannabe jihadi Kermiche repeatedly tried to get into Syria.

He spent time in prison mixing with other terrorists, including a young Frenchman who spent 18 months fighting with IS.

One pal said: “Everyone knew that kid was a time bomb. He was too strange.

“In the last few days he was asking everyone for money. Those who refused — and that was most of them — he called ‘heathens’.”

Police have yet to formally confirm his accomplice’s identity as the second killer was hit in the face by a hail of police bullets — making identification difficult.

Sources stated he was Petitjean from Aix-les-Bains, a small spa town near Lyon.

Cops have already found ID belonging to Petitjean — who had no criminal convictions — more than 430 miles away during a search at Kermiche’s home.

It has also come to light that Kermiche was free to kill after bleating to a soft judge: “I am not an extremist.”

His release under curfew came after he claimed: “I am a Muslim grounded in the values of mercy and goodness.”

The extraordinary comments came in psychological reports prepared for a French judge who was deciding whether to jail him.

Doctors had revealed the teenager was suicidal but the court ruled he was “aware of his mistakes”.

Kermiche’s medical evaluation took place between last October and February this year.

Police stood guard yesterday as people attended mass at the church and left tributes to Father Jacques.

The Pope yesterday acknowledged an internet campaign to have him declared a saint when he described Father Jacques as a “saintly priest”.
