Many Muslims in the Czech Republic often head to small prayer rooms, which are outside the reach of the Czech authorities and where police say some extremist groups tend to organize and congregate.
Not only Czech police officers say such prayer rooms are risky but some Muslims also believe they are as well.
Every Friday, Muslims gather in inconspicuous houses such as the one in the small village of Tuchom??ice in the northwest of Prague where they prepare to hold their traditional Friday prayer.
