A new round of talks between world powers and Iran opened on Tuesday in Almaty, Kazakhstan, to discuss the Persian nation's controversial nuclear program. 
Tuesday's talks between an Iranian team led by negotiator Saeed Jalili and representatives from the so-called 5+1 world powers  - the US, UK, France, China , Russia and Germany - are the first to take place since July 2012, when discussions ended without a breakthrough.
World powers, who accuse Iran of seeking to develop nuclear weapons, will use the talks this week to convince Tehran to curb its nuclear drive.
Iran has long since denied such charges, claiming it needs enriched uranium to make medical isotopes. 
Since 2010, Iran has been enriching uranium to a level of 20%, an important technological step toward being able to produce more highly enriched weapons-grade material.
The pariah state has repeatedly rejected Western calls to stop enriching uranium, insisting it is an inalienable right.
Western negotiators are expected this week to offer Iran incentives to compromise.
According to the BBC, EU spokesman Michael Mann said the offer will address "the international concern on the exclusively peaceful nature of the Iranian nuclear program," while also being "responsive to Iranian ideas."
"We've put some proposals forward which will hopefully allow Iran to show some flexibility," he said.
Reports suggest the proposals could include lifting sanctions on Iran in exchange for specific concessions.
Iran's Press TV reported that the Islamic Republic says it will offer "a new comprehensive package of proposals", without giving details.
