Vienna, July 1, IRNA � Foreign Minister Mohammad-Javad Zarif said on Wednesday that no deadline was set for reaching an agreement, adding that the talks are going on.

Zarif said that the seven countries' negotiating teams just continue their tasks, using every possible opportunity for achieving progress, ensuring progress in the talks.

The American and European sources had earlier announced that the talks' period had been extended for a week, but the Iranian officials argue that date (July 7) is merely due to the European and American sanctions' regulations as well as the restrictions that the Americans have for presenting the context of the deal to the US Congress before the summer holidays.

Asked about a visit to Iran of IAEA Director General Yukiya Amano, Zarif said that Amano is officially invited by Iran for a series of consultations.

Amano will arrive in Tehran tomorrow an is scheduled to meet the Iranian president and other high ranking officials.
