A senior US official said that the Saudi foreign minister has described his recent meeting with his Iranian counterpart in New York as good, and said that these talks will most probably continue in the Saudi capital.
The US official did not mention the exact date of Zarif's visit to Saudi Arabia.
On Sunday, Zarif met with his Saudi counterpart on the sidelines of the 69th Annual Meeting of the UN General Assembly in New York.
Zarif and Al-Faisal underlined that enhancement of Tehran-Riyadh relations will pave the way for their security cooperation to get rid of extremist groups.
"Both my Saudi counterpart and I believe that this meeting will be the first page of a new chapter in our two countries' relations," Zarif said after his hour-long meeting with the Saudi foreign minister.
The top Iranian diplomat expressed hope that this 'new chapter' would be a fruitful one, inclusive of the establishment of peace and security both in the region and in the world along with safeguarding the interests of not only the two nations, but also that of the entire Muslim nations.
Al-Faisal, for his part, said that he was aware of the significance and sensitivity of the emerged crisis (by the ISIL).
"We have an opportunity to encounter that crisis and we believe using this opportunity optimally, and refraining from making the past mistakes anew, we can reach agreement on ways for encountering this very sensitive crisis," he said.
He said that both Iran and Saudi Arabia are influential countries in the region and cooperation between them will leave undeniable effects on the establishment of peace and stability both in the region and in the world.
On Monday, Iranian President Hassan Rouhani in a message to Saudi King Abdullah expressed the hope that the brotherly relations between the two countries would expand everyday.
