Knifeman kills mother and sister in Paris suburb

French authorities said a knife attacker killed two people and seriously wounded one more in the Paris suburb of Trappes Thursday morning before being killed by police.

Police "neutralized" the attacker who is now dead, the Yvelines region's Twitter account said Thursday, adding that the police operation had ended.

The two people killed were the man's mother and sister. The third victim was a female passerby who was seriously wounded, The Associated Press reports.

The 36-year-old attacker had psychiatric problems, French Interior Minister Gérard Collomb told reporters.
