An El Al plane took off from Paris for Israel early Wednesday, carrying the bodies of three Jewish children and a rabbi gunned down in southern France, an airport source said.
The plane is expected to land in Tel Aviv at 5:35 am (0335 GMT), the source said.
Jonathan Sandler, a 30-year-old Frenchman, his two sons Arieh, 5, and Gabriel, 4 as well as seven-year-old Myriam Monsonego will then be buried later Wednesday morning at the Givat Shaul cemetery in Jerusalem, according to the Israeli embassy in France.
President Nicolas Sarkozy paid silent homage to the victims Tuesday at a school in Paris close to the city's Holocaust memorial, and afterwards admitted that authorities had as yet no clue as to the identity of the killer.
"Anti-Semitism is obvious. The Jewish school attack was an anti-Semitic crime," Sarkozy told reporters at the Paris school after meeting children.
French investigators fear the same gunman also killed three soldiers in two recent separate attacks and may strike again.
The three soldiers who died were French citizens of North African origin, while another who was critically wounded in the attack was black and from the French West Indies.
The bodies of the four victims of the Toulouse rampage were first flown to Paris with their families on Tuesday.
A ceremony will be held later Wednesday in army barracks at Montauban, near Toulouse, to pay homage to the two paratroopers from the 17th Parachute Engineering Regiment (17e RGP) and one member of the first paras who were killed earlier this month.
