ZURICH—Swiss police have found no radical Islamist or far-right motives by a gunman who killed himself after carrying out a shooting spree at Zurich mosque that wounded three worshippers, a top police official said Tuesday.
Authorities are still investigating the possible motive of the 24-year-old Swiss citizen of Ghanaian origin with a penchant for the occult who carried out Monday’s shootings in Switzerland’s largest city.
The incident had stirred concerns about possible extremist violence in the mostly peaceful Alpine country that, like others in mostly Christian Europe, has been wrestling with its relationship to its Muslim communities.
