Day of Mourning for Victims of Truck Attack in Sweden

Under sunny spring skies, crowds thronged the Sergels Torg plaza, a stone's throw from where a stolen truck mowed down strolling shoppers before slamming into the facade of the bustling Ahlens department store on Friday afternoon.

Sky sources say the device was a homemade bomb and Swedish media reports that the attacker "burned" himself while trying and failing to detonate the device.

Deputy chief prosecutor Hans Ihrman has requested that Stockholm District Court remand Rakhmat Akilov, 39, who is suspected of driving a truck into crowds on Drottninggatan in an attack which killed four people.

He said the countries of the four victims - two Swedes, a British man and a Belgian woman - had suffered "horrendous acts of terrorism, but we have also seen the strength and determination and power of our democratic societies".

The country held a minute's silence on Monday to honor those killed, with Swedish Prime Minister Stefan Lofven in attendance at a City Hall ceremony in Stockholm.

"We are all devastated by the untimely and tragic death of our talented, compassionate and caring son Chris", John Bevington, the victim's father, said in a statement.

The main suspect of the attack is a 39-year-old man from Uzbekistan, who had been facing deportation.

Police have described the suspect as an Islamic State group sympathiser who had gone underground in Sweden after his residency permit application was rejected a year ago.

Jan Evensson of the Stockholm police told reporters that "about five people" were being questioned and that a search for possible accomplices and sympathizers was ongoing. Police have also arrested a second suspect.

The chat reportedly ends with Akilov sending a video from the site of the terrorist attack in Stockholm.

"We have to improve the possibilities of ensuring this", he said, noting it was key to upholding "trust" in the asylum and migration system.

Nine people remained hospitalised, two of them in serious condition.

Akilov, a construction worker who had been refused permanent residency in Sweden, was arrested several hours after the attack in Marsta, a suburb north of Stockholm.

He allegedly had links to the Islamist group Hizb ut-Tahrir, newspaper Expressen reported.
