The Iranian capital, Tehran, is reeling from two terrorist attacks that targeted the Iranian Parliament and the Mausoleum of late Imam Khomeini and left at least 17 people dead and scores more injured. High on the list of reasons for breaking ties, Saudi Arabia named Qatar's friendly ties with Iran and Hamas. Riyadh has denied involvement in the attacks.
"We have intelligence that Saudi Arabia is actively engaged in promoting terrorist groups" in Iran's eastern and western borders", Zarif said at the opening of the Oslo Forum in Norway.
He gave no further details, but other officials said that four other alleged members of the gang had been killed in the southern Iranian province of Hormozgan, home to a substantial Arab minority.
"In the event that America wages a war against Iran, all of that country's military bases in the region will be in danger, as Iran is capable of hitting targets with its missiles within a range of 2,000 kilometers", Major General Yahya Rahim Safavi said on Wednesday.
Zarif, during his meeting with Kenyan Foreign Minister Amina Mohamed on the sidelines of the Oslo Forum, called for Kenyan efforts to help resolve the ongoing diplomatic crisis in the Middle East by initiating dialogue between Qatar and Saudi Arabia.

Oettinger, a European Commission budget and human resources commissioner, expressed doubt about the talks starting as planned. Steven Fielding, a professor of politics at the University of Nottingham, called her "a zombie prime minister".
"It is absolutely imperative.to establish a permanent mechanism for consultation, conversation and conflict resolution in our region, using some variation of the Helsinki approach", said the foreign minister, in reference to the 1975 Helsinki Accords.
Zarif told the forum that recent Saudi officials' remarks against Iran are a "direct threat and very risky provocation".
He mentioned that Iran-Pakistan gas pipeline was a significant project to develop good relations with Iran, but the USA and Saudi administrations have been pressuring Islamabad to abandon the project.
"We believe that the rest of the global community will make it clear - as it has done already to them - that it considers the nuclear deal as a multilateral agreement and not a bilateral agreement between Iran and the United States", Zarif said. "We are not intimidated by these moves".
