The Duisburg Central Mosque, which is affiliated with the Turkish-Islamic Union for Religious Affairs (DITIB), on Saturday got the threatening letter, which included both a swastika and the word "NSU 2.0," referring to a neo-Nazi group responsible for a string of murders.
Yusuf Aydın, head of the DITIB Central Mosque Association, said they shared the racist letter with the police and filed a criminal complaint.
"We are deeply saddened. We demand that the perpetrator or perpetrators be apprehended and brought to justice as soon as possible," Aydin said.
He added that the mosque has already received over a dozen threatening and insulting letters.
