Iranian President Hassan Rouhani will present a plan for creating security in the Gulf in cooperation with other countries in the region when he attends the United Nations General Assembly in New York this week.

Saudi Arabia and the United States accuse Iran of carrying out attacks on Saudi oil facilities on September 14 in what was the largest-ever assault on oil facilities in the world's top oil exporter.

Iran denies involvement in the attack, which was claimed by Yemen's Houthi movement, a group aligned with Iran and currently fighting a Saudi-led alliance in Yemen's civil war.

"This year we will present a plan to the world at the United Nations that the Islamic Republic of Iran in cooperation with the countries of the region can create security for the Persian Gulf and the Oman sea with the help of the countries of the region,” Rouhani was cited as saying on his official website.

He did not provide further details.

US President Donald Trump on Friday approved sending American troops to bolster Saudi Arabia's air and missile defences after the September 14 attacks on Saudi oil sites.

Rouhani said the presence of foreign forces in the region will create insecurity for oil and shipping.

Saudi Arabia has called the strikes on Abqaiq and Khurais facilities as a test of global will to preserve international order, and will look to form a united front at the UN General Assembly.

“We are not someone who will violate the borders of others just as we will not allow anyone to violate our borders,” Rouhani said at a ceremony commemorating the anniversary of the start of the Islamic Republics 1980-1988 war with Iraq, according to his official website.

Long-range missiles, speed boats and warships were shown in video footage on state TV as part of the ceremonies commemorating the anniversary of the war with Iraq.

The military parade marked the 39th anniversary of the eight-year war with Iraq that began when Saddam Hussein invaded Iran in 1980.

Similar parades were held in many major cities and towns across the country including the port city of Bandar Abbas near the Strait of Hormuz.

State TV showed scores of Iranian fast attack boats, as well as air defence and other military equipment. It also carried images of Iranian Revolutionary Guard naval forces rappelling down the side of a sailing ship.

The chief of the powerful Revolutionary Guard, Gen Hossein Salami, threatened the “destruction of any aggressor” against Iran the day before.

Iran has long sought the evacuation of Western and US forces from Arab Gulf countries, seeing it as a potential threat to the Persian nation.
