Former Israeli President and Nobel Peace Prize laureate Shimon Peres has addressed the UN's education, science and culture agency in Paris to promote peace, as Europe reels from a spate of extremist attacks.

The 92-year-old statesman met Friday with UNESCO's Director-General Irina Bokova who signed a memorandum of understanding with the Peres Center for Peace that drives work on peace education and intercultural understanding.

With a frail voice, Peres said that democracy means that everyone has "the equal right to be different" and that to move forward people shouldn't cling to the past.

Peres met with French Prime Minister Manuel Valls Thursday, saying that Israel could lend Europe its technical expertise in the fight against extremism. Later Friday he'll meet with President Francois Hollande.
