If the two flights are booked separately, or if there are two or more connection airports inside Schengen, they will need a (full) visa (and one hour is very unlikely to be enough to make the connection).
Otherwise, with a single hop inside Schengen and the two flights on the same ticket, they will stay airside (in the sterile international transit area) and wonβt have to go through passport control.
Some nationalities require an airport transit visa in that situation, but this is not the case unless they transit through France and arrive from an airport in Armenia, Azerbaijan, Georgia, Ukraine, Belarus, Moldova, Turkey or Egypt.
So at this time a Russian national arriving from Israel will not need an ATV. Note that can change over time, sometimes with very little notice.
