Another stab on a bus in Germany

A woman slaughtered six people on a bus headed for a festival in western Germany. Police have arrested 32-year-olds, while saying there is no evidence that there is political or religious motive for the attack.

Three of those attacked are in critical condition, police have added.

The knife attack occurred in Sieghen. The bus was headed there and there were about 40 people in it.

Six people are ages 16 to 30, the AP reported. 

Siegen's massacres occurred a week after the knife attack on Solingen, where an Islamic extremist from Syria is accused of killing three people and causing injuries to eight others.

Police have said the woman arrested was German nationals and had nothing to do with migration.
