Five people have been shot at a school in Sweden as authorities warned the danger was not over while armed officers rushed to the scene. Armed police descended on the Risbergska School, an adult educational institute in the city of Örebro some 200 km (125 miles) west of Stockholm on Tuesday.

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.

One day after the killings at an adult educational center, some gathered to lay flowers and come to grips with the violence.
