Selena Gomez has been branded a "coward" by a Jewish organization ... after embroiling herself in controversy over the Israel-Hamas war.

Speaking to TMZ, Mitchell Bard for the Jewish organization American-Israeli Cooperative Enterprise (AICE) lambasted Selena for falling victim to the intense pressure put on celebs to boycott and demonize Israel.

He tells us instead of speaking on the massacre of 1,400 Israelis and the taking of 240 hostages, including the elderly, disabled, women and children as young as 9 months ... Selena's priority lies with her business, which was threatened after the Rare Beauty's CEO followed pro-Israel accounts.

The org also details its disappointment over her choosing to "pacify bullies" hoping to boycott Rare Beauty by "taking the popular position that Palestinians who have been sacrificed by Hamas are the victims" ... with a pro-Palestine-leaning statement shared to RB's IG.

In stark contrast ... the very same IG post delights Alia Malak, a founding member of the Palestinian organization, Boycott, Divestment, and Sanctions (BDS), who tells TMZ, "Selena Gomez is one of many thousands of artists and cultural figures worldwide calling for ceasefire, justice and accountability, joining Hollywood figures, leading Black scholars and artists, Jewish writers and artists, prominent authors, visual artists, and many others."

They add, "When UN experts and others are warning of an Israeli genocide against Palestinians in Gaza, these artists are on the right side of history. Palestinians call on artists and arts organizations to speak out loudly for a ceasefire, and for an end to oppression, as many had done against apartheid South Africa, to contribute to freedom, justice, and equality."

This comes after Rare Beauty's statement on IG acknowledged the slaughter of 1,400 Israelis ... saying that attacks on civilians are wrong ... but alluding their main concern was "protecting Palestine civilians."
