Watch as Czech President Petr Pavel attended a church service for victims of the Charles University shooting.
The Czech Republic declared Saturday, 23 December, a day of mourning after 14 people were killed and 25 were wounded after a shooting at a Prague university by a 24-year-old student.
Police are working to uncover the motive behind the attack, which is believed to be the worst mass shooting in the country’s history.
Mr Pavel tweeted on Friday morning, saying: “My thoughts are still with families of the victims, injured and those who had to fight for their lives at the Faculty of Arts. No one can imagine the fear and mental strain they went through yesterday. From the bottom of my heart I would like to thank for the sincere condolences and words of support, which come from all around the world.”
