In the past decades, Finland has witnessed two major deadly school shootings.
In November 2007, a 18-year-old student armed with a semi-automatic pistol opened fire at the premises of the Jokela high school in Tuusula, southern Finland, killing nine people. He was found dead with self-inflicted wounds.
Less than a year later, in September 2008, a 22-year-old student shot and killed 10 people with a semi-automatic pistol at a vocational college in Kauhajoki, southwestern Finland, before fatally shooting himself.
In the Nordic nation of 5.6 million, there are more than 1.5 million licensed firearms and about 430,000 licence holders, according to the Finnish Interior Ministry. Hunting and gun ownership have long traditions in the sparsely-populated northern European country.
Responsibility for granting permits for ordinary firearms rests with local police departments.
Following the school shootings in 2007 and 2008, Finland tightened its gun laws by raising the minimum age for firearms ownership and giving police greater powers to make background checks on individuals applying for a gun licence.
