UN Secretary General Antonio Guterres visited the grave site of former President Shimon Peres.
"Shimon Peres was a close friend, one of the most important leaders in the world, and I had the honor of getting to know him very closely, we spent many hours together, and one meeting I remember especially - when we met with Nelson Mandela in Lisbon. As far as I'm concerned it was a meeting with two giants, Nobel winners, who worked all their lives to promote peace in the world, "he said.
