Hawzah News Agency- One of the letters was sent to a mosque in Dortmund, which is run by DITIB, and the other to a Moroccan Islamic Mosque near Düsseldorf.

Both incidents, which took place on Thursday, have been reported to the police, according to the statement, Hawzah News reported.

Last week, some DITIB mosques were evacuated and searched after receiving bomb threats via email.

However, no explosive devices were found and normalcy was declared after a few hours, according to the report, but Friday prayers, which are usually held around 1 p.m., were canceled.
