In months and years preceding the incident , Europe has seen a number of vehicular terror attacks against pedestrians ( 2014 Dijon , 2014 Nantes , 2016 Nice , 2016 Berlin , 2017 Westminster , 2017 Stockholm ) . While no similar terror attack had taken place directly in the Czech Republic , the 1973 vehicular rampage perpetrated by Olga Hepnarová remains to this day the largest mass murder in the country ( with 20 victims , of them 8 fatal )
