Hundreds of Ukraine Jews are reportedly planning to flee the country due to the increasingly unstable living conditions.
Ukraine is still in a conflict with Russia over Crimea and the eastern Donbass province. Some 40,000 Russian troops massed along the Crimea-Ukraine border last week, prompting Ukraine to place its own troops on high alert ahead of the 25th Ukraine Independence Day.
Separatist forces helped Russia annex Crimea in 2014 in a vicious conflict that left thousands dead.
The International Fellowship of Christians and Jews reports its Kiev office has received more than 1,700 inquiries from Ukraine Jews over the past month about aliyah to Israel, which the organization helps facilitate.
An estimated 260,000 Jews are allegedly still living in the war-torn country. According to the NGO, there are about 5,000 Jews in the disputed Donbass region who are eligible to immigrate to Israel.
Many Jews in the cities of Donetsk and Luhansk, both in Donbass, are unable to reach the area of Ukraine where they can collect their basic state pensions of some $40 per month, due to attacks and military checkpoints.
Local authorities in Donbass recently jailed a Jewish community official who helped the Fellowship administer local humanitarian aid, and then exiled him west to the Ukraine capital, Kiev.
As often happens in times of war, the Jewish community has been caught in the crossfire between Ukraine forces and pro-Russian separatists in eastern Ukraine and Crimea.
