It was entitled "Peace Between Religions" and was due to start Thursday and last for three days.
The ministry did not give a reason but reports say it was because of the presence of Israeli Jews.
A group called "Move Boycott" took credit for scuttling the conference.
An anti-Israel group issued a statement saying, "This conference is taking place in light of the official Arab acceleration of normalization with the Zionist entity, and the constant threat to Jordan by this enemy, as well as a clear encroachment on our national sovereignty, and daily encroachment on the sanctities under the protection and guardianship of Jordan, and comes at a time when the Zionist enemy terrorized the Palestinian people and its war on Gaza, which has not ended, and the blood of its martyrs has not dried up yet."
Here as the first page of the schedule.
No one in Jordan seems embarrassed by this debacle as far as I can tell.
