He made the remarks while speaking to IRNA exclusively on the sidelines of the two-day conference which ended on Wednesday evening issuing a 24-point final statement.
Al-Zawawi hailed the role of Tehran conference in showing legitimacy of the Palestinian nation as well as their oppression to the world countries.
The ambassador also appreciated Iran’s efforts to encourage the Islamic countries to pay attention to the Palestinian issue.
He said that moving the US embassy from Tel-Aviv to al-Quds, expansion of Israeli settlements and occupation of more Palestinian lands as well as banning the Muslim call to prayer are all examples of the US-Zionist plots against Palestinian nation.
The official noted that US hostility, in particular that of the new US president Donald Trump, towards Muslims is becoming more evident day by day.
Al-Zawawi said that unity among the Palestinian groups is a must for establishment of an independent state of Palestine with the city of Quds as its capital. He stressed that the Tehran conference was a good opportunity to resolve differences among Palestinian groups.
The Palestinian envoy further referred to the Supreme Leader of Islamic Revolution Ayatollah Seyyed Ali Khamenei's call for dissolution of the Zionist regime and said that the Third Intifada would be another defeat for the Zionist regime.
The official underlined continuation of the path of martyrs until complete restoration of the rights of Palestinians.
