Several people have been shot dead at a shopping centre in the southern Finnish city of Espoo, near the capital, Helsinki, Finland's media report.
Four people have been killed, according to the website of the Finnish national broadcaster, YLE, though this has not been confirmed.
Police and ambulances are at the scene, but there are no reports of the gunman having been stopped.
The incident is Finland's third major shooting in the past two years.
Thursday's bloodshed reportedly broke out at about 1000 local time (0800 GMT) at the Sello shopping centre.
A witness said an employee of the Prisma grocery store was left lying on the floor of the shop, and that a man dressed in black was seen walking toward the Citymarket store.
A separate, unconfirmed, report said one person had been shot twice in the head and another in the stomach.
Parts of the shopping centre were closed and trains were not stopping at the local railway station, YLE said.
Gun laws tightened
There is a long tradition of hunting in Finland, which has vast areas of forest and wilderness, but until recently gun crime has been rare.
But two deadly shootings in recent years focused attention on gun laws in a country where young people were permitted to own and use a firearm at 15 years of age if they had parental consent.
In November 2007, an 18-year-old went on a gun rampage at his school in Tuusula, killing seven pupils and a teacher, before turning the gun on himself. He had posted a video warning of the attack on the internet.
Then, in September 2008, a 22-year-old trainee chef killed 10 people at a college before killing himself.
He, too, had put a video on the internet showing himself shooting a gun. After doing that he was interviewed by police, but they decided it was not sufficient reason to revoke his gun licence.
After the second attack, stricter rules on permits for pistols and revolvers were introduced.
Handgun permits would no longer be granted to first-time applicants, the interior ministry said.
Instead, they must train for at least a year at a gun club before being allowed to apply for a permit.
All applicants must also provide a note from a doctor about their mental health and sit an interview with police.
Third major one in 2 years with a few smaller ones in between. What degree of mentalness drives these people to do this shít?
