By Johan Ahlander and Simon Johnson OREBRO, Sweden (Reuters) -Swedish police found three rifles near the body of the gunman amid a chaotic scene they described as an "inferno" after 11 people were killed and several wounded in the country's deadliest mass shooting,

Police investigating Sweden's worst mass shooting were still trying to establish a motive as to why a lone gunman opened fire at an education campus in the southern city of Orebro, killing 10 people.

Around 10 people were killed in a school shooting in Örebro. The damage at the crime scene was so extensive that investigators were unable to be more definitive, said Roberto Eid Forest, head of the local police.

Sweden's right-wing government said on Friday it would seek to tighten gun laws in the wake of the country's deadliest mass shooting at an adult education centre where the attacker appeared to have used several of his own licensed rifles.

Sweden's worst ever mass shooting this week has raised questions about the country's gun laws and widespread gun ownership.
