"The Zionist regime's cruel and inhuman policies are the main cause of all tensions, insecurities and crises and formation of terrorism in the region," Hassanpour said on Wednesday.
Although international organizations have condemned the Zionist regime for occupying Palestinian territory and called for end to occupation and return of refugees, the regime, with US extensive support, is ignoring international law and continues to expand its occupation and trampling upon Palestinian rights, he said.
The ambassador condemned the US move to recognize Quds as the Zionist regime's capital and transfer its capital to the holy site, saying that provocative move has fuelled violence and bloodshed, and the UN General Assembly in December 2018 opposed the US President's decision by a majority of votes.
Deal of the century which is mainly supported by the US contradicts accepted democratic values and norms, as well as approvals of the United Nations and other international organizations, Hassanpour said.
His remarks were made on the eve of the International Quds Day on May 22.
The International Quds Day is an annual event opposing Israel's occupation of Beitul-Muqaddas. Anti-Zionist rallies and demonstrations are held on the last Friday of Ramadan in Muslim and Arab countries around the world, specially in Iran, as well as a large number of non-Muslim states.
Due to the outbreak of coronavirus in the world, the International Quds Day will be commemorated differently without holding gatherings and rallies in most countries.
The International Quds Day was started by the late Founder of the Islamic Republic, Imam Khomeini, in 1979 as a way of expressing solidarity with the Palestinians and underscoring importance of the holy Quds to Muslims.
