The Organization for Security and Cooperation in Europe has condemned a series of death threats against Artan Haraqija, an RFE/RL journalist who has been reporting on radical Islamic groups in Kosovo.

Jean-Claude Schlumberger, the OSCE mission chief in Kosovo, called on September 18 for authorities in Pristina to bring to justice those who have threatened Haraqija and other journalists in Kosovo.

Haraqija, who also works for the Indeksonline website, received the latest in a series of death threats after appearing on a Kosovar TV program called “Rubikon” on September 16.

Haraqija worked on a joint report about Kosovo’s radical Muslims with “GazetaExpress” journalist Visar Duriqi, who also has received death threats for his work.

On September 17, police arrested 15 Muslim leaders across Kosovo for allegedly recruiting fighters for Al-Qaeda and the Islamic State militant group.
