From the BBC:

Swiss voters have supported a referendum proposal to ban the building of minarets, official results show.

More than 57% of voters and 22 out of 26 cantons - or provinces - voted in favour of the ban.

The proposal had been put forward by the Swiss People's Party, [[SVP), the largest party in parliament, which says minarets are a sign of Islamisation.
