There has been a sixth night of rioting in Sweden's capital, Stockholm, despite police reinforcements being deployed.
The US and UK meanwhile warned their citizens to avoid affected areas.
The riots began on Sunday in Husby, a deprived, predominantly immigrant area in the north-west of the capital.
On Friday, Stockholm's police force was reinforced by specially trained officers from the cities of Gothenburg and Malmo, both of which have seen rioting in recent years.

THE REASON FOR THE STOCKHOLM RIOT

Police fatally shot a 69-year-old man in an apartment in north Stockholm on Monday evening after responding to calls that a man armed with a machete was menacing the neighbourhood.


Police were called to an address in the Husby district, north of central Stockholm, around 6pm on Monday following several reports that a knife-wielding man was roaming around the area.

"He had a knife or a machete. When we arrived, this person disappeared into an apartment," Stockholm police spokesman Lars Byström told the TT news agency.

The man then stood on the balcony of the apartment and threatened police.

"He screamed at police from the balcony that he wanted to kill them," a neighbour told the Expressen newspaper.

Negotiators were called in and police subsequently learned that a woman was also in the apartment. After negotiations failed to yield any results, police then decided to break down the door and storm the flat in hopes of securing the woman's safety.

"Then the person in question appeared holding a machete. Officers felt cornered and threw a flash grenade so they could overpower the man. That didn't work either and they then felt forced to open fire," said Byström.

It's unclear how many officers fired shots and exactly how many shots were fired, but according to witnesses, police fired five or six shots before things went silent.

"We saw the flashes when they shot. Even if you'd never sees an actual shooting before, you knew what it was," a witness told Expressen.

The 69-year-old man was taken to hospital where he was pronounced dead from his gunshot wounds.

The woman in the flat escaped the incident without sustaining any physical injuries, according to police. The woman's relationship to the man remains unknown.

The incident is now under investigation by prosecutors from the Swedish National Police Crimes Unit (Riksenheten för polismål).
