French police secure a street after a Knife attacker killed two persons

BBC says a man armed with a knife has attacked passersby, killing one and seriously injuring two others, before being shot by police in Trappes, west of Paris.

Police tweeted that an operation was underway in Trappes, with a security perimeter in place.

BBC reported that the man first sheltered in a house after attacking people with a knife and then was shot by police.

French Interior Minister Gerard Collomb tweeted that the attacker had been neutralized without saying if he was dead.

Daesh group has claimed responsibility for a knife attack in a Paris suburb that has left two people dead.

The group posted its claim for the Thursday attack through its Aamaq news agency in a post shared on social media channels.

The agency says the attack in Trappes was motivated by calls from the Daesh leadership to attack civilians in countries at war with the extremist group.

Hours earlier, the Daesh group’s leader, Abu Bakr al-Baghdadi, urged followers to attack enemies everywhere by all means, including in knife attacks.

Two French officials say the two people killed in a knife attack west of Paris were the mother and sister of the attacker, according to news reported.

The French interior minister reconfirmed that a man who killed his mother and sister in a knife attack west of Paris had “serious psychiatric problems.”
