DUSHANBE: Ex-Soviet Tajikistan said on Tuesday it plans to install metal detectors and surveillance cameras in more than 70 mosques in the capital Dushanbe over government fears of extremist attacks. A government source speaking on condition of anonymity told AFP the measure was meant to “track the contingent praying at the mosque, to identify among believers potential followers of Salafism,” referring to an ultra-conversative brand of Sunni Islam. “Salafis behave ostentatiously during prayers in mosque and can be distinguished by their beard and form of dress,” the source said.
