Andrew Garfield broke down in tears as he honoured his family members believed to have perished in the Holocaust.

The 41-year-old actor delved into his family history for an episode of genealogy series Who Do You Think You Are? and he traced his roots back to Poland, revealing his Jewish great-grandfather Ludwig Garfinkel managed to flee to London in 1910, but three of Ludwig's sisters stayed behind and are believed to have been murdered at Nazi death camp Treblinka.

Andrew visited the site of Treblinka and wept as he placed three stones on a memorial dedicated to all those from the family's hometown of Kielce who were killed at the camp.
