Kermiche and a second unidentified attacker stormed the church, forced priest Jacques Hamel to kneel before they killed him, and captured the bloody assault on film, according to a nun who escaped the assault.
"They forced him to his knees. He wanted to defend himself. And that's when the tragedy happened," said the nun, identified as Sister Danielle.
"They recorded themselves. They did a sort of sermon around the altar, in Arabic. It's a horror," she told BFM television. Molins said the other hostages were used as human shields to block police from entering.
Both attackers were shot dead by anti-terror police units as they ran outside the sanctuary shouting "Allahu Akbar!" One had three knives and a fake explosives belt, Molins said; the other carried a kitchen timer wrapped in aluminum foil and had fake explosives in his backpack.
