TOPSHOTS A Roma man walks with a pickaxe in the remains of a house demolished by a bulldozer in a Roma suburb in the city of Plovdiv on April 25, 2014. About fifty illegally built Roma houses and buildings were destroyed in the city of Plovdiv on Friday. Bulgaria's 700,000-strong Roma minority is highly ghettoised and discriminated against, and violent incidents -- both between Roma and between Roma and non-Roma -- are frequent.
