A book of condolences was opened at Stockholm's City Hall on Saturday (April 8) following the truck attack on a pedestrian shopping street on Friday (April 7) that saw four people killed and over a dozen wounded.
Swedish police have arrested a 39-year-old Uzbek man on suspicion of ramming a hijacked beer delivery truck into crowds in central Stockholm, in what they called a terror crime.
People queued patiently in the early afternoon outside the iconic building to sign the book.
Flags around the city were flown at half-mast and on Sunday (April 9) a gathering will be held at Sergels Torg in the centre of Stockholm, close to where the incident took place.
A minute's silence will also be observed all over Sweden at midday on Monday (April 10), according to the city website.
