The BBC's Stephen Evans in Stockholm: "The whole policy of immigration and integration is being questioned"
There has been a sixth night of rioting in Sweden's capital, Stockholm, despite police reinforcements being deployed.

Cars were set alight in poor suburbs inhabited largely by immigrants, although the unrest was reportedly not as serious as on previous nights.

The rioting also spread outside the capital for the first time on Friday, with youths torching vehicles and buildings in two towns.

The US and UK meanwhile warned their citizens to avoid affected areas.
Outside the capital, the violence spread to previously unaffected towns, he adds.

In the central town of Orebro, about 25 masked youths set fire to three cars and a school, while in Sodertalje, just outside the capital, an empty building was torched, police said. Suspected arson attacks were reported in Linkoping, south of Orebro, as well.

Police in Orebro were pelted with stones and at least one officer was slightly hurt by broken glass, Swedish media reported.

Our correspondent says there is now a debate in Sweden about immigration.
The UK Foreign Office advised people to stay away from large gatherings in the Stockholm suburbs of Husby, Hagsatra, Ragsved, Skogas, and to take care and monitor local reports.
The riots began on Sunday in Husby, a deprived, predominantly immigrant area in the north-west of the capital.

It is believed they were sparked by the death of an elderly man nearly a week before, who was shot by police after he allegedly threatened to kill them with a machete.
