Overview
- Three Turkish mosques in Leeuwarden, Groningen, and Harderwijk received anonymous letters urging a stop to “islamisering.”
- The letters referenced past attacks, including 9/11, and explicitly cited the upcoming start of Ramadan as the reason.
- Police units in Noord- and Oost-Nederland are in contact with mosque boards, remain extra alert for new reports, and currently see no direct danger or identified offence.
- The Islamitische Stichting Nederland shared the letters with its network and asked mosque boards to file police reports.
- Leaders at the Harderwijk mosque called the letter hurtful and generalising, pledged calm outreach, and noted similar hate mail targeted Dutch mosques last autumn.
