The final statement is compiled following repeated extending of negotiations in 100 pages.

Foreign ministers of the G5+1 began a meeting in Vienna at early hours Tuesday morning local time to make necessary coordination about the nuclear deal.

The meeting began following a tripartite meeting held by Foreign Minister Mohammad Javad Zarif, US Secretary of State John Kerry and EU foreign policy chief Federica Mogherini.

Meanwhile, deputies of foreign ministers from Iran, US and European states are meeting to discuss final changes of the text of the nuclear agreement.

Zarif had earlier made clear more work was needed to seal a nuclear accord and indicated the work could not be finalized tonight.

He also tweeted, 'if an Iran Deal reached, triumph of diplomacy means we all will have won when we all could have lost. Plain and simple; no spin needed.'
