11:40 a.m.

The mayor of Munich has declared a day of mourning for the victims of Friday's shooting in the Bavarian capital.

Dieter Reiter says the city is "shocked and aghast at this terrible act."

In a statement Saturday on Facebook, Reiter expressed his condolences to the victims, their family and friends, and thanked security forces for their work.

Ten people, including the alleged shooter, were killed in the attack.

Reiter said Saturday would be "a day of mourning, not of celebration" and that all public festivals in the city over the weekend had been canceled.

"These are difficult hours for Munich," he said, adding that the city's citizens had shown great solidarity toward each other. "Our city stands united."
