Nursultan Nazarbayev, Kazakhstan's president, has approved a new law aimed at putting an end to religious extremism.

The law forces all religious organisations to re-register and bans prayer in state institutions such as schools and prisons.

The country's chief imam believes that preventing Muslims from praying will antagonise the Kazakh public.
