Update:

Issac Levy died at age 69 in January 2005. His body was transferred by the Red Cross from Afghanistan to Israel (where he has family members) for burial.

Zebulon Siman-Tov, 65, left Afghanistan in 2021 after the Taliban takeover, saying that he fears for his life and immigrated to the US. He formally divorced his ex-wife after years of being separated but still legally married.

Why did the two fight? Each claimed ownership to a Torah scroll in the last synagogue of Afghanistan at the time. They complained to the Taliban authorities, who decided to imprison both. During their imprisonment, the synagogue was robbed and the Torah scroll was stolen. The Taliban got so tired of their fighting that they threw them out of jail.
