Representatives of 39 nations have urged governments to do more for Holocaust survivors in the remaining time they have.

The nations concluded their two-day conference in Prague by calling for the benefits they get not to be taxed, the development of special pension programs and the sale of heirless Jewish property to finance social welfare programs.

They say "it is unacceptable for those who suffered so grievously ... to live out their last years in deprivation."

Stuart Eizenstat, a special adviser to the U.S. Secretary of State on Holocaust issues, says the message is urgent because half of the current 500,000 survivors probably won't be alive within seven years. He told The Associated Press on Wednesday about 50 percent of the survivors live under the poverty line.
