Flowers and flags and thousands greeted Iran’s negotiators on their return to Tehran after reaching a landmark agreement with world powers on Iran’s nuclear programme.

In Europe France’s Foreign Minister, Laurent Fabius said EU foreign ministers will meet in a few weeks and put forward proposals to partially lift some sanctions.

On the streets chants of “No to war, sanctions, surrender and insults,” rang out.

“Mr. Zarif who was appointed by Mr. Rohani had new things to tell the world in the past few months. That’s why he managed to reach a deal in the talks. We are here to thank Mr. Zarif and to say that people support the government and the negotiations,” said Mostafa Shoorab who was among the crowd and lives in Tehran.

Iran’s Foreign Minister Mohammad Javad Zarif went on state television saying they would take the necessary steps to keep the temporary agreement on track.

“In a few weeks maybe before the end of the Gregorian year we may start the first phase. Surely it is impossible to do all the terms of the agreement in one day. The first phase is a six-month period. We are not supposed to do this in too many steps, but some measures will have priority over others,” he told viewers.

In early trading oil prices fell with Brent crude dropping by more than two percent. Iran is the world’s fourth largest oil producer.

Under the agreement Tehran is set to receive sanctions relief worth around seven billion dollars on sectors including precious metals. The sum is equivalent to 1.4 percent of its entire national income.
