Finnish investigators today said a quiet, young chemistry student was behind a deadly bomb blast at a busy shopping mall outside Helsinki.

Seven people died and 80 were injured after a bomb ripped through a crowded shopping mall near Helsinki.

One of the seven people killed in a blast in Helsinki is suspected of being responsible for the explosion.

Six people were killed and 55 injured last night in an explosion at a packed shopping mall in Finland that caused part of the building to collapse.
