If there is any country benefiting from the Islamic State group's terrorism, it is Israel. That claim comes from a senior diplomat in Iran, as he asks Muslim nations in the Middle East to unite for the sake of region's future.

Hossein Amir-Abdollahian, Iran's deputy foreign minister for Arab and African affairs, said that Israel and the Islamic State group, also known as ISIS or ISIL, were the “two sides of the same coin.” He said that Israel was the main sponsor of terrorism and added that the Jewish country was the “winner of the acts of terrorism and destruction by the ISIL terrorist group in the region.”

Abdollahian said Wednesday that the extremist forces in the Middle East have a primary purpose of stealing the wealth of Muslim countries and destroying the resistance front against Israel. He said that terrorism would not exist in the Middle East if Muslim countries in the region were united.

The Iranian official blamed the United States and other Western nations for being “insincere” in fighting terrorism. He said that those countries were responsible for “the intensification of Israel’s crimes and further insecurity of the region.”

Iranian President Hassan Rouhani earlier said that the entire population of the country would “shout its hatred” for Israel during the International Quds Day rallies Friday. He said that people would tell the world that the Muslim nations were never going to forget Israel’s occupation of the Palestinian territory, Fars News reported.

Abdollahian also criticized Saudi Arabia’s aggression in Yemen. “The belligerent attitude of Saudi Arabia, as a Muslim country, against Muslim Yemeni children and women is reminiscent of Zionists’ actions in [the war on the besieged] Gaza Strip and brings shame to the Islamic and Arab world,” Press TV quoted him.

According to the United Nations High Commissioner for Human Rights, Saudi attacks in Yemen killed at least 5,133 people and injured around 15,000 others in Yemen since March.
