Belgrade residents have lit candles and laid flowers the day after a deadly school shooting in the Serbian capital.
The incident killed eight children and a security guard in what President Aleksandar Vucic called "one of the most difficult days" in the country's recent history.
Police have detained a 13-year-old suspect in connection with the shooting and have arrested his parents.
"I cried all day yesterday," says Mileva Milosevic, whose son used to be enrolled in the school.
