A Muslim boy cleans carpets for praying on a street in front of a destroyed illegally built mosque at Zemun Polje district in Belgrade, Serbia June 2, 2017. Local authorities demolished the mosque on the outskirts of Belgrade after Serbian police secured the area in a pre-dawn action on May 26, ahead of the Muslim holy month of Ramadan, despite protests by local Muslims and Islamic clergy. The construction of a two-storey mosque without a minaret in the Zemun Polje neighbourhood started in 2014 even though the authorities had refused to grant it a construction permit.
