This is the best summary I could come up with:

German authorities said that have received an alert that a group may have been planning an attack on the Cologne Cathedral, the DPA news agency reported Saturday.

Authorities have not elaborated on the alert they received, saying police in the German city will take special protective measures.

Sniffer dogs were brought in to search the premises after the evening mass service and visitors will be screened before entering the church, Michael Esser, the chief of police, said in a statement.

The German daily Bild reported that officials in Germany, Austria and Spain had  received indications that an Islamist group was planning several attacks in Europe.

Authorities in Cologne have recommended visitors avoid carrying bags or arriving too early for mass at the church.

The Cathedral, the largest Gothic church in northern Europe, was designated a UNESCO World Heritage Site in 1996.
