"We have raised it (security) a little extra in places where we have children and young people," Lena Posner-Koeroesi, who heads the Official Council of Swedish Jewish Communities, told the Svenska Dagbladet newspaper.
Posner-Koeroesi, whose council represents Jewish congregations across Sweden, said personnel at the Jewish schools and other institutions run by the congregations were "well-prepared" and had "routines for how to go out with information and for what kind of measures are needed" in such situations.
There has been no apparent panic among parents and children, he added.
The security hike came after a gunman opened fire at the Ozar Hatorah school in Toulouse, killing two boys aged three and six and their father, a 30-year-old religious studies teacher, who witnesses later said was trying to protect the children, along with the 10-year-old daughter of the director of the school.
The gunman, who also critically injured a 17-year-old boy, escaped on what
witnesses said was a powerful scooter.
Last week, three French paratroopers - all of North African descent - were killed in two similar incidents in the same region, also involving a scooter-rider wielding the same powerful .45 calibre handgun.
