Iran has rejected what it calls "baseless" accusations made at an Arab summit, saying Saudi Arabia had joined the United States and Israel in a "hopeless" effort to mobilize regional opinion against Tehran, state media reported.

Axar.az reports citing IRNA.

Saudi Arabia's king told an emergency Arab summit on Thursday that decisive action was needed to stop Iranian "escalations" in the region following attacks on oil assets in the Gulf, as American officials said a US military deployment had deterred Tehran.

"Foreign Ministry spokesman Abbas Mousavi ... rejected the baseless accusations by the heads of certain Arab countries ... and said: 'We see the Saudi effort to mobilize [regional] opinion as part of the hopeless process followed by America and the Zionist regime against Iran'," state news agency IRNA reported on Friday.

The comments by King Salman Abdul Aziz came as Saudi Arabia hosted in Mecca emergency meetings of the Gulf Cooperation Council (GCC), the Organisation of the Islamic Conference (OIC) and the Arab League to counter what it said was Iran's growing influence.

A Gulf-Arab statement and a separate communique issued after the wider summit both supported the right of Saudi Arabia and the United Arab Emirates (UAE) to defend their interests after the attacks on oil pumping stations in the kingdom and tankers off the UAE coast.

But in a sign of regional tensions, Iraq, which has good ties with neighboring Iran and the US, said it objected to the Arab communique, which stated that any cooperation with Tehran should be based on "non-interference in other countries".

Reporting from Tehran, Al Jazeera's Zein Basravi said Iran knows that the final communique at the meeting is "not necessarily the real opinion of all the members of the GCC".

"He [Mousavi] also rejected and condemned allegations against Iran for interfering in the affairs of neighboring countries, as the Saudis said in the meeting," he said.

Basravi said the Iranian leader also said "Saudi Arabia was misusing its role as host for the OIC meeting to spread ... divisive policies among Muslim leaders".
