Midway through the tenth season, Ziva's estranged father, Eli, resurfaces in the episode "Shabbat Shalom" in the hope of healing their relationship. During his time in Washington, he is also secretly meeting with a Palestinian born Iranian (with an unclear connection to the Iranian government) whom he knows from childhood. Together, they hope to initiate the beginning of a peace agreement between Israel and Iran. At the end of the episode, while having a Shabbat dinner at Director Vance's house, an unknown shooter opens fire on the house, killing Eli and fatally wounding Vance's wife, who dies in the hospital. The shooter evades capture and then kills himself with cynide in a cigarette, when Gibbs and David corner him. Upon discovering her father's body, Ziva breaks down sobbing and praying in Hebrew. The CIA use these events to blow up the Iranian. Ensuring peace dies with them.
