Zarif, Ashton, Kerry to meet in Vienna on Wednesday

Trilateral talks on Tehran's nuclear program will be held in Vienna on Wednesday, involving Iranian Foreign Minister Javad Zarif, EU foreign policy chief Catherine Ashton and US Secretary of State John Kerry, RIA Novosti said.

"The idea is that there will be a bilateral meeting between Catherine Ashton and Zarif, then they will be joined by Secretary of State Kerry. That's going to happen tomorrow. And the hope is that they just make some progress," Ashton's spokesperson Michael Mann said Tuesday.

Mann noted that talks of a possible extension of the November 24 deadline are "speculations," and that the deadline "is still 5-6 weeks away, we have to see what happens in the talks."

On Tuesday, Iranian nuclear negotiators arrived in the Austrian capital for nuclear talks at the political leadership level. In addition, Zarif held a three-hour meeting with Ashton, described by Ashton's spokesman as "useful."

It was also agreed that the next round of talks between Iran and the P5+1 group, comprising Russia, the United States, the United Kingdom, France, China, and Germany, will be held on October 16.
