Serj Tankian has made an impassioned plea for an end to the conflict in Gaza.
Tankian wades in on Gaza debate
SOAD singer calls for end to West Bank conflict
The System Of A Down frontman says in a post on his Facebook page that Israel's "occupation" of the West Bank is hypocritical, considering the horrors suffered by the Jewish people in the Holocaust.
He says the song Occupied Tears on his solo album Harikari was written about the Gaza conflict.
Tankian adds: "It's time to end this misery known as the Israeli Occupation of Gaza and the West Bank. Occupied Tears was written about this and the hypocrisy of a people who have gone through the horrible atrocities of the Holocaust now serving as occupiers of another people.
"One more thing – calls for anti-semitism should never be used to cloak honest discussion of these issues, especially here in the US."
Tankian and SOAD haven been outspoken on political issues throughout their careers. The singer previously said artists have a responsibility to speak to the truth.
