A woman walks past broken shop windows in a shopping centre following a protest in the Biryulyovo district of Moscow October 13, 2013. Demonstrators, some chanting racist slogans, vandalised a shopping centre and scuffled with police in a Moscow neighbourhood on Sunday after the killing of a young man that residents blamed on a migrant from the Caucasus.
