Austere brand of Islam on rise in Europe, stirring concerns

Salafism, an Islamic movement based on a literal reading of the Quran

Salafism, an Islamic movement based on a literal reading of the Quran, is on the rise in France, Germany and Britain. European authorities say the latest Islamic trend is becoming an increasing concern.

Its imams preach austere piety; its tenets demand strict separation of sexes — and some of its most radical adherents are heeding the call of jihad in Syria and Iraq.

Experts say Salafis in these countries have been waging a campaign of stealth to take over mosques. In Germany, authorities consider all Salafis as extremists.
