Police in France have arrested 19 suspected Islamists and seized weapons in a series of dawn raids, President Nicolas Sarkozy says.

The raids were in Toulouse, the home of gunman Mohamed Merah, and other cities.

Merah, who killed seven people in three separate attacks, was buried in Toulouse on Thursday after being killed in a shoot-out with police on 22 March.

Police have been hunting possible accomplices but sources said there was no direct link with the raids.

Merah's brother, Abdelkader, has been charged with aiding him and police are hunting a third man said to be involved in the theft of a scooter that Merah used in all the killings.

Mr Sarkozy told Europe 1 radio after Friday's raids: "It's our duty to guarantee the security of the French people. We have no choice. It's absolutely indispensable."

The raids were carried out by the domestic intelligence agency, the DCRI, with the help of the elite Raid police commando group, Agence France-Presse news agency reports.

Several of the raids were in Toulouse, particularly the Mirail quarter, sources told AFP.

But there were also raids in Nantes, which is believed to be a centre for the Forsane Alizza (Knights of Pride) group, to which Merah had been linked by some French media.

It is a Salafist group that was dissolved by the interior ministry in an earlier investigation.

Other arrests took place in Lyon, Marseille, Paris, Nice and Le Mans.

Police sources told AFP that some weapons had been seized, including at least one Kalashnikov rifle.

After Merah's killings, President Sarkozy ordered police to evaluate the level of danger posed by those known to sympathise with radical Islamists.

Mr Sarkozy told Europe 1 on Friday that arrests of suspected radical Islamists "would continue and that will allow us to expel from our national territory a certain number of people who have no reason to be here".

He added: "What must be understood is that the trauma of Montauban and Toulouse is profound for our country, a little - I don't want to compare the horrors - a little like the trauma that followed in the United States and in New York after the September 11, 2001 attacks."

Mr Sarkozy is in the midst of a presidential election campaign, seeking a second term in office in the polls on 22 April.

An opinion poll late on Wednesday suggested Mr Sarkozy was now ahead of main challenger Francois Hollande in first-round voting intentions - by 30% to 26% - and had narrowed Mr Hollande's lead in the largely expected run-off vote on 6 May.

Merah, 23, was buried at the Cornebarrieu cemetery in Toulouse on Thursday. His body was accompanied by around 15 men, although it was not clear who they were.

Toulouse's mayor had said it was "inappropriate" for Merah to be buried there, but Algeria, where his family is originally from, had refused to accept his body.

Merah died in a police assault on his flat in Toulouse on 22 March after a 32-hour siege. He had killed three soldiers in two separate attacks before shooting dead three children and a teacher at a Jewish school.

Merah is said to have told police he wanted to avenge Palestinian children and to attack the French army because of its foreign interventions.
