Jailed French Preacher Suspected of Radical Plans An official says French police detained a radical preacher in December who was ready to lead dozens of young Muslims from the southern city of Nice to Afghanistan. The official said Monday that Omar Diaby, a 37-year-old Senegalese man, was meeting up with two followers on Dec. 9 when he was stopped by police for an ID check that upended his plans. The official says Diaby remains behind bars as police investigate his role in the suspected network and in trafficking in stolen car parts. The official, who is familiar with the investigation, spoke on condition of anonymity because he was not authorized to reveal the information. The news has echoes of the case of Frenchman Mohamed Merah, who traveled to Afghanistan before going on a killing spree this month that took seven lives. PARIS (AP) - France's president has dismissed the far-right's use of a recent killing spree as evidence of a need for tougher immigration laws, saying Monday the call makes no sense in the wake of the massacre by a "monster" who was French-born. Nicolas Sarkozy, facing a tough re-election campaign this spring, has veered to the right to garner votes, talking a tough line on immigration and the place of Islamic customs in France. But he criticized one of his opponents on Monday - National Front candidate Marine Le Pen - for suggesting lax immigration laws led to the shootings of 23-year-old Mohamed Merah. Last week, police tracked Merah to his apartment and after a more than 30-hour siege shot him dead as he jumped from a window, guns blazing. Sarkozy has sought to paint Merah's killing spree, which left seven people dead in southwestern France in just over a week, as an isolated incident from which France shouldn't draw too many conclusions. "We can't equate Mohamed Merah - who was born in France, and is French - with the children of immigrants who arrive by boat," Sarkozy told France-Info radio. This Mohamed Merah, if you'll excuse me, was a monster. Investigators are also looking into whether Merah's older brother, Abdelkader, helped in the killings of the rabbi, three Jewish children and three paratroopers. Abdelkader is in custody, and on Sunday was handed preliminary charges for complicity in murder and terrorism. While Sarkozy rejected the link between the spree and immigration, he added that he still stands by his calls to tighten border controls, saying that France can't afford to provide benefits to illegal immigrants, and a flood of arrivals is overwhelming the country's means for assimilating newcomers. This weekend Le Pen ramped up her rhetoric, promising to drastically reduce the number of immigrants coming to France's shores and warning that more such attacks await France if it does not shut its doors. How many Mohamed Merahs are in the planes and on boats that arrive each day in France filled with immigrants? How many Mohamed Merahs are among the non-assimilated immigrants?" she shouted to cheers at a rally in western France on Sunday. Le Pen promised, if elected, to bring "radical Islam to its knees." Authorities said that Merah, during the standoff with police, told them he wanted to bring France "to its knees" with the spree that began in the city of Toulouse with the murder of a soldier.
