Tehran, July 1, IRNA � US Secretary of State John Kerry is going to stay in Vienna for the final talks on Iran�s nuclear program until at least July 7, a source in the US delegation told Sputnik Tuesday.

Earlier in the day, media reports citing the US State Department said the negotiations between the P5+1 group of countries and Iran on Tehran�s nuclear program had been extended until July 7.

'I can confirm that Kerry is staying here. We have not announced him leaving at any time, 'the source said, answering a question on whether Kerry would leave before July 7.
