On Thursday, German authorities arrested three alleged members of Islamic State suspected of planning an attack in downtown Düsseldorf. French police had already arrested a fourth suspect, also from Syria, in February.
The four men had entered Europe as refugees and were supposed to be joined by six more people to carry out the attack in Düsseldorf, Der Spiegel reported, citing the fourth suspect, Saleh A. who is currently in French custody.
According to the plan, two people were going to detonate suicide bombs and others would kill people with guns and explosives, Der Spiegel said. Similar attacks hit Brussels in March and in Paris in November, which killed a total of 164 people.
Düsseldorf’s historic center, nicknamed the longest bar in the world, is lined with pubs and is known for its popularity among tourists.
