BERLIN—Three more people were detained Sunday in connection with a reported threat of an attack on the Cologne Cathedral over the holidays, German authorities said.
The detentions came only days after a 30-year-old Tajik man was detained in relation to an alleged plot to attack the world-famous cathedral by Islamic extremists in the western German city.
The suspects were detained in the western cities of Duisburg, Herne, and Dueren in the state of North Rhine-Westphalia, and their apartments were also searched there. No details about their identities were released.
All of the detained suspects—including the Tajik who was arrested last week—allegedly belong to a larger network that included people across Germany and in other European countries, according to Cologne police chief Johannes Hermanns, German news agency dpa reported.
The attack was supposed to have been carried out with a car loaded with explosives, local media reported.
Cologne police said in a Sunday news conference that the cathedral’s underground parking garage had been searched and that explosives detection dogs had been deployed—but nothing was found. Since the early morning, the entrance and exit of the underground garage had also been checked for suspicious activity.
North Rhine-Westphalia’s Interior Minister Herbert Reul called the latest detentions a “success, for which I would like to thank the investigators.”
Islamic extremists have always been active, but they are currently more active than usual and the Catholic cathedral was a prime target for them, Mr. Reul said, according to dpa. “The police always try to be a few steps ahead,” he added.
Police had received information about a planned attack on Cologne Cathedral shortly before Christmas. The attack was to be carried out on New Year’s Eve.
The city’s world-famous cathedral has been under high protection for a week and the threat led to the closure of the house of worship for tourists since Christmas Eve.
Usually, more than 100,000 tourists visit the cathedral in the last week of the year. In recent days, only worshippers were allowed to enter the building for Mass, but they had to go through thorough security checks involving sniffer dogs.
On Sunday evening, around 1,000 police officers were on duty around the cathedral as revelers began celebrating the end of 2023.
Mr. Reul encouraged people to celebrate and not stay at home despite the attack threat.
“Islamist terror is still a threat on German streets,” he said. “We have often suppressed that. And whenever there is a one-off event like this, we are all very electrified again.”
However, it would be wrong to panic, said Mr. Reul. “I say: Celebrate! Behave yourselves! Take care—and enjoy the transition into the new year.”
