"The Security Council, due to a lack of political will, is not capable of fulfilling its duties within the framework of the organization's Charter to defend the rights of the Palestinian people," Gholam-Ali Khoshroo said at a Security Council meeting on Friday.
He reiterated the Non-Aligned Movement (NAM)'s support for the cause of Palestine and the inalienable rights of its people and stressed the importance of establishing an independent Palestinian state.
The NAM member states believe that the Security Council's lack of political will has led to the international body's failure to fulfill its responsibilities regarding the Palestinian issue, Khoshroo, whose country holds NAM's rotating presidency, stated.
He further pointed to the violation of international human rights by the Israeli regime, particularly in its aggression on Gaza last year, saying that the Zionist regime has definitely committed war crimes according to confirmed evidence.
"This regime should be accountable for its deeds, but no international measure has been carried out yet against this regime," the Iranian envoy said, adding that the inaction cannot be justified in any way.
Israel started its latest war on the Gaza Strip in early July last year. The offensive ended on August 26, 2014, with a truce that took effect after indirect negotiations in the Egyptian capital, Cairo.
Nearly 2,200 Palestinians, including 577 children, were killed in Israel's 50-day onslaught. Over 11,100 others - including 3,374 children, 2,088 women and 410 elderly people - were also injured.
The Zionist regime has imposed a complete air, ground, and naval blockade on the Gaza Strip since 2007. The crippling siege has caused a serious decline in Gazans' standard of living, unprecedented levels of unemployment and unrelenting poverty for the Palestinian enclave's 1.8 million residents, which has been described by media as the world's largest open-air prison.
