Saudi Crown Prince Mohammed bin Salman and Iranian President Ebrahim Raisi talked on the phone for the first time ever, pledging united support for the Palestinian cause.

The conversation lasted for roughly 45 minutes, according to SAMAA, and it focused on the war in Gaza. Iranian state media reported that the two affirmed the "need to end war crimes against Palestine," according to Reuters. The Saudi Press Agency reported that Salman affirmed his support for the Palestinian cause and urged against the targeting of civilians.

"He also stressed - may God protect him - the Kingdom’s firm position towards supporting the Palestinian cause and supporting efforts aimed at achieving a comprehensive and just peace that guarantees the Palestinian people’s access to their legitimate rights," the Saudi Press Agency said in a statement.

The two sides also committed to supporting military de-escalation. Sentiment about the need to end the targeting of civilians appeared to be focused against Israel, while the two stressed the joint support for the Palestinians.

The nature of the call, and the fact that it even took place, shows a substantial change in Saudi-Iranian relations following a Chinese-brokered peace agreement between the two earlier this year. The rivalry between the Sunni and Shiite powers has laid waste to much of the region, playing a substantial role in conflicts from Syria to Yemen.

Iran has maintained a decidedly bellicose relationship with Israel, even as Saudi Arabia appeared to warm toward the Jewish state. Hamas's surprise attack against Israel on Saturday, and the ensuing Israeli retaliation, appear to have ended immediate hopes for the normalization of Israeli-Saudi relations, which seemed a distinct possibility.

So far, the war in Gaza has claimed the lives of 2,300 Israelis and Palestinians, according to the Associated Press.
