Meanwhile AFP reports that world powers seek breakthrough in Iran nuclear talks.
Iran and major powers scrambled to finally nail down an elusive nuclear accord ahead of a Monday deadline, with China calling for "no more delays" in the marathon talks.
No deal could be "perfect" but "conditions are already in place for a good agreement", China's Foreign Minister Wang Yi told reporters as he arrived for discussions in the Austrian capital, speaking through an interpreter.
Foreign ministers from the so-called P5+1 -- the United States, Britain, France, Germany, Russia and China -- were gathering "to bring the negotiation to its conclusion," he added.
"We believe that there cannot and should not be further delay."
Iranian Foreign Minister Mohammad Javad Zarif said he believed there should be no further extension to the talks but he would negotiate as long as needed.
"I always believe there shouldn't be any extension but we could work as long as necessary to finish this," Zarif said as he met Wang.
Iran's President Hassan Rouhani will address the nation about the nuclear talks on state television on Monday night, a media official told AFP in Tehran.
The official IRNA news agency said Rouhani would speak when the nuclear talks have concluded, but it did not give a time.
