Due to the seriousness of the threat, French authorities launched a security operation involving explosive detection dogs inside and around the cathedral.

Notre Dame, one of the world’s most iconic religious and architectural landmarks, had only recently reopened in December 2024.

According to officials, no incidents have occurred following the threat, but strict surveillance remains in place.

Authorities have reiterated their commitment to safeguarding both the faithful and one of France’s most treasured heritage sites.
