A woman stabbed and wounded six people on a bus in western Germany on Friday night, according to local police and media reports. Three of the victims are in life-threatening condition.
The stabber, a 32-year-old woman, is a German national, although it is unknown to the public at this time if she holds another citizenship.
Police have said that they are searching for a motive for the attack but claim to have seen no indications it was terror-related.
Some 40 people were traveling on the bus to attend a festival, according to DW News.
Attacks in Germany
The attack came only a week after a similar incident in Germany, in which three people were killed and eight wounded by a knife attack carried out by a Syrian national.
The incident has left Germany reconsidering its asylum and security policy.
Pressure has increased on the coalition government to reverse that suspension after a fatal stabbing linked to Islamic State at a city festival a week ago and another knife attack in June when an Afghan man killed a German policeman.
