Zechariah Baumel (Hebrew: ????? ??????; 17 November 1960 – 1982), also known as Zachary Baumel, was an American-Israeli soldier in the Israel Defense Forces.
On the night of June 10–11, 1982, during the Battle of Sultan Yacoub in the 1982 Lebanon War, his unit was attacked and he and five other comrades were declared missing.
One had been killed and was later found buried in Syria, and two were located alive in Syria and returned to Israel a few years later.
But Baumel and two others remained unaccounted for.
Until his death in 2009, Baumel's father Yona kept his son's case in the public eye, traveling around the world to uncover leads to verify the persistent rumors that his son was still alive, and criticizing the Israeli army for not pursuing the case vigilantly.
On April 3, 2019, Russian President Vladimir Putin announced that the Russian army, in coordination with the Syrian military, had found Baumel's remains.
The military operation was a result of a two-year cooperative effort between Israel and Russia to return bodies of missing Israeli soldiers buried in Syrian territory formerly controlled by ISIL; the operation was code-named Operation Bittersweet Song (Hebrew: ??? ?????, Zemer Noogge).
Baumel's remains were handed over to Israeli Prime Minister Benjamin Netanyahu in an official ceremony at the Russian defense ministry in Moscow on April 3 and interred the following day at the Mount Herzl military cemetery in Jerusalem.
The whereabouts of the other missing soldiers remain unknown.
