The top Iranian diplomat made the remarks at a joint press conference with his Syrian counterpart Faisal al-Mekdad in the Syrian capital of Damascus on Friday.
Syria is Amir-Abdollahian's third stop in a regional tour that has already taken him to Iraq and Lebanon.
He revealed that he had met earlier in the Lebanese capital Beirut with the secretary general of the Resistance movement of Hezbollah, Sayyed Hassan Nasrallah, and a number of other Resistance leaders.
"I was informed [at that meeting] that the Resistance has put all possible scenarios before itself, and [that the Resistance groups] were in high spirits," the Iranian official said.
Amir-Abdollahian warned that the Zionist regime and its allies were trying to realize a "mass carnage" in Gaza through their continued disruption of the flow of food, water, and electricity towards the territory.
"I am willing to announce this message to the leaders of the Muslim and Arab countries in a loud voice that today, the oppressed people of Gaza are in need of immediate international assistance towards the removal of the humanitarian siege and cessation of the Zionists' crimes," he said.
He criticized the Arab League for issuing a "bleak" statement on the situation that is faced by the people of Gaza, denouncing the grouping for its "vague and ambiguous positions."
The official finally hoped that the foreign ministers of the Organization of Islamic Cooperation (OIC) would meet soon in the Iranian capital of Tehran or elsewhere to address Gaza's situation.
