Three men believed to be linked to Mohamed Merah were arrested in southern France.
Two of men were arrested Tuesday in Toulouse by a French police anti-terror unit, the French news service AFP reported.
A third person was arrested on Wednesday morning in the nearby town of Castres.
Merah, a 23-year-old radical Muslim, killed a rabbi and three children in an attack on the Ozar Hatorah Jewish school, now Ohr Hatorah, on March 19, 2012. The slayings came a few days after Merah gunned down three French soldiers in two drive-by shootings from a scooter near Toulouse. He was shot dead on March 22 during a standoff with police.
French police have arrested and released several people and questioned dozens in connection with the shootings.
