Police say the possession of firearms has risen in the Czech Republic last year.
In 2017, the number of firearms permits increased to 303,000.
That is 2,700 more than in 2016 and an increase of 11,000 compared with 2015.
Fears over terror attacks, immigration and personal assaults have caused the surge, Czech police say.
The total number of guns, rifles and other firearms kept at home by Czechs has risen to around 850,000. That is an increase of 13.3%, or 100,000 compared to five years ago.
