Swedish royals King Carl XVI Gustaf and Queen Silvia have laid flowers at a school campus which this week became the scene of the country's worst ever mass shooting.
Eleven people were killed when a gunman opened fire at Campus Risbergska, in central Sweden's Orebro, on Tuesday.
Six others injured in the shooting, five of which remain in a critical condition.
Police said there was no evidence the suspect, a 35-year-old unemployed recluse who was among the dead had "ideological motives".

The royals were joined at a memorial service by Sweden's Prime Minister Ulf Kristersson.
"A grieving process is hard to do alone," the king told reporters afterwards.
"I think all of Sweden feels it has experienced this traumatic event."
Town reeling after 'dark day'
Orebro's mayor, John Johansson, told broadcaster SVT he and many other residents were "very afraid", a day after the attack.
"That it could happen in Orebro, that was totally unexpected," he said.
Prime Minister Ulf Kristersson, who joined the king and queen on the trip to Orebro, said February 4 would "forever mark a dark day in Swedish history".
"We are a country in mourning and we must all come together," he said.
"Together, we must help the injured and their relatives bear the grief and weight of this day."

Students who were in the class at the time of the attack have told of their narrow escapes as the shooting unfolded.
"A guy next to me was shot in the shoulder. He was bleeding a lot. When I looked behind me I saw three people on the floor bleeding," a school student, Marwa, told Swedish broadcaster TV4.

"Everyone was shocked. They said: 'Go out! Get out!'."
One of the teachers at the school, Maria Pegado, said she was concerned about the impact of the shooting on some of her students.
"Many of them have fled from countries where things like this happen and now they experience it here. It is horrible."
