A SUICIDE bomber blew herself up yesterday as police raided a Paris flat in search of the mastermind behind Friday’s terrorist attacks.

A man was also killed by “projectiles” and grenades in the swoop by a Research, Assistance, Intervention and Deterrence (Raid) anti-terrorist squad in the northern suburb of Saint-Denis.

A seven-hour siege followed the pre-dawn assault, ending in the arrest of seven suspects. Fifteen residents including children were escorted from the block.

However, police said they believed one more suspect was still hiding in the building.

Prosecutor Francois Molins said the raid had been launched after information from tapped telephone conversations, surveillance and witness accounts indicated that chief suspect Abdelhamid Abaaoud was hiding there.

Authorities also sent out a Europe-wide alert for a Citroen Xsara car that could be carrying suspect Salah Abdeslam.

But authorities could not immediately confirm whether Islamic State militant Mr Abaaoud, a Belgian of Moroccan descent, had been killed or arrested.

The raid was only one of many overnight across the country, with a total of 25 arrests and the seizure of 34 firearms.

That brought the figure since Friday to 414 raids, 60 arrests and 75 guns, with 118 additional people placed under house arrest under new emergency powers.

Parliament is expected to extend the state of emergency for three months later this week.

The legislation to extend the powers also includes a measure allowing authorities to close “any association or gathering” — which notably includes mosques and community groups — that is “glorifying terrorism.”

Europe remained on a high state of alert yesterday following the attacks.

The main terminal at Copenhagen’s international airport was evacuated after “a suspicious bag” was found. Services on commuter railway and underground lines to and from the airport were also suspended.

In Sweden, security service SAPO raised the country’s terror alert to the second-highest level after receiving “concrete information,” but no details were given.

Two Air France flights bound for Paris from the US were diverted on Tuesday night — one to Salt Lake City and one to Halifax in Canada — after threats were received after they had taken off.

n Isis said yesterday that it had murdered two hostages, Norwegian Ole Johan Grimsgaard-Ofstad and Chinese Fan Jinghui, after demanding a ransom for their release two months ago.
