People gathered outside the burnt out DITIB [Turkish-Islamic Union for Religious Affairs] Koca Sinan Camii mosque in northern Berlin on Sunday morning, after a fire broke out at the venue earlier that day.
Berlin’s Interior Senator Andreas Geisel visited the scene. Standing outside the mosque he said, “I can only call on people to live with each other peacefully, here in Berlin.”
Chair of the Alliance for Innovation and Justice Haluk Yildiz maintained that this was an act of terror, rather than an arson attack. He said, “This is a terror attack on the largest Turkish community in Europe.”
Yildiz went on to criticise German politicians for not visiting the site of the fire. He said: “I’d also wished that the CDU leader, the SPD leader, all those so-called democrats were here, so that they can also say that they distance themselves from this. It’s not enough that just the Interior Senator is here.”
Translated from Dutch NOS TV, 11 March 2018:
Turkish mosques and clubhouses set on fire in Germany
There were also fire attacks in Sauerland and in the town of Itzehoe north of Hamburg. In Sauerland three Molotov cocktails were thrown at a home and in Itzehoe a window of a mosque was smashed and fire set at a Turkish greengrocer’s shop. A passerby warned the residents in the building above the store that there was a fire ….
On Friday there had already been arson in a mosque in Baden-Württemberg. The chairman of the representative organization Türkische Gemeinde in Deutschland called this a terrorist attack. The police deal with that case as attempted murder and is looking for five suspects.
