Prime Minister Netanyahu just spoke to French President Hollande.
Hollande confirms to him that four hostages are dead, and says 15 were freed from the siege at the Paris kosher grocery store. Several of them are said to be in critical condition.
Netanyahu offers any assistance Israel can provide. He calls for the international community to unite in the fight against Islamist terror. He says Islamic extremism has to be tackled, too, at its sources of funding, and also that its incitement efforts needs to be tackled and thwarted.
Netanyahu also asks Hollande to maintain heightened security arrangements at Jewish institutions.
