TEHRAN, June 13 (Xinhua) -- Iran's Foreign Minister Mohammad Javad Zarif said Tuesday that Saudi Arabia is supporting terrorism in Iran's borders, Tehran Times daily reported.

"We have intelligence that Saudi Arabia is actively engaged in promoting terrorist groups" in Iran's eastern and western borders," Zarif told the opening of the Oslo Forum in Norway on Tuesday.

Zarif told the forum that recent Saudi officials' remarks against Iran are a "direct threat and very dangerous provocation."

The remarks by Zarif partially referred to the comments made by Saudi Arabia's deputy crown prince, Mohammed bin Salman Al-Saud, in May, who said Riyadh would bring "the battle" into Iran.

Also, just hours before the deadly attacks by the Islamic State (IS) in Iran's capital Tehran last Wednesday, which killed 17 people, Saudi Foreign Minister Adel Al-Jubeir claimed that Iran was the world's leading supporter of terrorism and must be punished.

On Tuesday, commander of Iran's Islamic Revolution Guard Corps (IRGC) said that Saudi Arabia has been behind June 7 terrorist attacks in Tehran.

"We have obtained accurate intelligence that Saudi Arabia supported the terrorists and asked them to carry out attacks in Iran," Maj. Gen. Mohammad Ali Jafari was quoted as saying by semi-official Mehr news agency.

In the meantime, deputy Chief of Staff of the Iranian Armed Forces Brig. Gen. Massoud Jazayeri said Tuesday that Saudi Arabia and the United States "direct and support such acts of terrorism against regional countries," Tasnim news agency reported.

The recent terrorist attacks and other hostile moves by the enemies cannot undermine the Iranian nation's resolve to continue fighting terrorism, Jazayeri said.

Top Iranian political leaders have gestured the United States and Saudi Arabia of being behind the recent twin deadly attacks in Tehran.
