Naim spoke after the Israel Defense Forces announced on Thursday the killing of Hamas leader Yahya Sinwar.
"It is very painful and distressing to lose beloved people, especially extraordinary leaders like ours, but what we are sure of is that we are; this is the outcome for all people who fought for their liberty," Naim said.
