Protesters have burned Israel flags outside the DC embassy where a US airman set himself on fire in a fatal pro-Palestine protest.

Aaron Bushnell, 25, succumbed to his injuries after lighting himself on fire as he screamed 'Free Palestine' on Sunday in a demonstration he streamed on Twitch.

A vigil was held outside the embassy where hundreds gathered to protest the Israel-Hamas war and call for a ceasefire on Monday night.

Protesters set Israeli flags ablaze and carried posters that said Bushnell's last words, 'Free Palestine.'

Other signs said 'Israel bombs babies' and that Bushnell was 'killed in protest of Israel's brutality.' Some lit candles and left notes and flowers for the 25-year-old.

Secret Service and DC Metro Police Officers stood outside the embassy that's front lawn is lined with flags and posters of the hostages taken from the October 7 terror attack.

In the aftermath of Bushnell's self-immolation, pro-Palestine activists including presidential candidates Jill Stein and Cornel West have expressed their admiration for the engineer.

Stein wrote on X: 'Rest in power Aaron Bushnell. May his sacrifice deepen our commitment to stop genocide now.' 

West added: 'Let us never forget the extraordinary courage and commitment of brother Aaron Bushnell who died for truth and justice!

'I pray for his precious loved ones! Let us rededicate ourselves to genuine solidarity with Palestinians undergoing genocidal attacks in real time!'
