At least seven persons were killed and another three were wounded after a teenager opened fire in his high school on Wednesday in southern Finland. To most Americans might seem unbelievable, but this is the first time that the northern European country is dealing with such a case.

"At this moment it’s seven (deaths) or more, higher," Dr Eero Hirvensalo, a member of the medical response team, told Reuters.

The boy was about 18 years old and the high school that just entered the country’s history is the Jokela High School. These facts were released by Heidi Hagman, assistant to the municipality director in Tuusula, some 30 miles north of the capital, Helsinki, in an interview with the Associated Press.

 According to her statement there were three wounded and the shooter was still inside the school at which at least 400 students aged between 12 and 18 were enrolled.

"Some of the pupils have managed to escape from the school but others are still inside,'' Hagman said.

Senior Constable Tuomi Juola confirmed the fact that there was shooting inside the Jokela High School, but other than that there was nothing else to declare at that stage.

According to Finland’s Prime Minister, Matti Vanhanen, the situation is "extremely tragic'' and the government will hold a meeting as soon as possible.

A few hours before the shooting took place, a video was posted on YouTube to announce the upcoming tragedy. The video is set to hard-driving music and depicts a photo of a school that appears to be Jokela High School, then the still photo fragments to reveal a picture of a man pointing a gun at the camera.

The YouTube video was entitled "Jokela High School Massacre - 11/7/2007" and was posted by Sturmgeist89. "Sturmgeist" means the spirit of the storm in German and probably depicts how the troubled boy must have felt.
