French lawmakers have paid tribute to the victims of an Islamic extremist attack at a supermarket in southern France.

Lawmakers at the National Assembly in Paris observed a minute of silence Tuesday for the four people who died in Friday's attack.

Prime Minister Edouard Philippe said since January 2015, French intelligence services have thwarted 51 attacks. In addition, 17 other attacks have failed and 11 have taken place.

He says "this is a difficult combat we will have to fight, a terrible combat, a hand-to-hand struggle, in which we will have successes — we had some — and in which we might have failures."

A national memorial is being held Wednesday in Paris to honor Lt-Col. Arnaud Beltrame, the officer who lost his life after swapping himself with a hostage.
