Numerous children on the photos above were 3-7 years old when WWII started. They never started ordinary schools. On the top picture there are Jewish children, liberated in Bergen-Belsen concentration camp and brought to Sweden by UNRRAs action in June-July 1945, later known as White Boats.
Numerous children left thereafter Sweden in January 1947 on S/S Ulua, later Haim Arlosorof. The ship was later stormed by British Navy commando troops at the shore of Haifa and all passengers including children, were imprisoned on Cyprus (lower picture). Several children groups were later in 1947 let into Eretz Israel where their education continued.
