Excerpt:
Authorities in Basel have denied two Muslim teenage girls a Swiss passport because they refused to participate in school swimming lessons and residential camps on religious grounds.
The case, which occurred last year but was made public by broadcaster SRF on Monday, involved two sisters, aged 12 and 14.
Speaking to the broadcaster, Stefan Wehrle, president of the naturalization committee involved in the decision, said young people wishing to become Swiss citizens must prove they are meeting the requirements of the Swiss education system.
