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.
