Pictured: One of the men who slit throat of elderly French catholic priest named

One of the knife-wielding men who went into a church in Normandy and slit the throat of an 84-year-old elderly priest has been named as Adel Kermiche, 19.

Kermiche had been arrested twice in both France and Switzerland for attempting to flee France to join ISIS and was being monitored with an electronic ankle tag.

Despite having been released early from prison, Kermiche's bail conditions allowed him to move about freely without supervision between 8.30 am and 12.30 pm daily.

Kermiche and his accomplice killed the priest between 9 am and 11 am. Both of them were shot and killed by police marksmen as they emerged from the building shouting 'Allahu Akbar' following the attack.

Father Hamel

Sister Danielle, a nun who escaped said:

'They told me "you Christians, you kill us". They forced him to his knees. He wanted to defend himself. And that's when the tragedy happened. 

Kermiche was living with his parents in the Saint-Etienne-du-Rouvray area as Father Hamel.

In a press conference, the police said they are still seeking to identify the second attacker and raids were underway.
