One of the deadly bombings at an Egyptian church on Sunday could have been even more deadly.
Three police officers died after preventing an attacker from entering a cathedral in Alexandria. Instead, he blew himself up outside the church, killing the officers and more than a dozen other people, Nile International reports, citing Egypt's interior ministry.
A CCTV recording shows a man trying to enter the cathedral, then being ordered by police to leave before an explosion engulfs the screen.
WATCH | Here's the moment right before the Alexandria bomb went off. An official can be heard saying "That's him, coming, showing here at the gate, he tried to pass from the side, and the security made him go back, and the x-ray went off, and he blew himself up."
The slain officers were Ahmed Ibrahim, Brigadier General Nagwa El-Haggar and Emad El-Rakiby, head of the local investigation department. A photo of El-Rakiby went viral on Reddit after news of his death broke.
Pope Tawadros II, the leader of the Coptic Church, had held Palm Sunday services in the cathedral shortly before the attack. His aides said he escaped unharmed.
The death toll in the attacks reached 43 by Sunday afternoon. A bomb in a church in Tanta killed 27 people and injured 78. The Alexandria bomb killed 16 people and injured 21. ISIS claimed responsibility for the attack.
