Danger of chemical attack: French PM

French PM Manuel Valls has warned that France could face chemical or biological attack from terror groups, as MPs debate extending the state of emergency after the Paris attacks, reports BBC.

Belgian police are meanwhile raiding six properties in and around Brussels, linked to suspected Paris attackers Bilal Hadfi and Salah Abdeslam.

It remains unclear whether the suspected organiser of the attacks was killed in Wednesday`s raid in Paris.

Friday`s attacks killed 129 people.

Mr Valls was addressing the French parliament ahead of a vote to extend the state of emergency by three months.

He told MPs that "terrorism hit France, not because of what it is doing in Iraq and Syria ... but for what it is".

"What is new are the ways of operating; the ways of attacking and killing are evolving all the time," the prime minister said.

"The macabre imagination of those giving the orders is unlimited. Assault rifles, beheadings, suicide bombers, knives or all of these at once."

Mr Valls also called for Europe to adopt measures on sharing information about airline passengers as a way of protecting collective security.

French authorities say that they foiled another attack in Wednesday morning`s raid on a flat in the northern Paris suburb of Saint Denis.

Eight people were arrested in the raid, in which police fired over 5,000 rounds of ammunition, but those arrested did not include Abdelhamid Abaaoud - who investigators suspect was the ringleader of the attacks.

At least two people were killed in the raid, one of them a woman who blew herself up with a suicide vest.

She is widely reported to be Hasna Aitboulachen, a cousin of Abaaoud.

The Washington Post quoted unnamed European officials as saying Abaaoud, a 27-year-old Belgian, was killed in the raid, but French authorities told AP the identities of the dead remain unclear.
