On this day last year, 25-year-old US Air Force serviceman Aaron Bushnell self-immolated outside the Israeli embassy in Washington, DC, repeatedly screaming "Free Palestine" until he collapsed.

His final act of protest sent shockwaves across the world, a haunting reminder of the urgency and moral weight of the cause he gave his life for.
