Iran has indicated it is prepared to make concessions on its nuclear programme in talks with the U.S. in return for the lifting of sanctions and recognition of its right to enrich uranium, as it seeks to avert a U.S. attack, Reuters reported. 

Both sides remain sharply divided -- even over the scope and sequencing of relief from crippling U.S. sanctions -- following two rounds of talks, a senior Iranian official told Reuters.

However, Reuters is reporting for the first time that Iran is offering fresh concessions since their talks ended last week, when the sides appeared far apart and heading closer to military conflict. Analysts say the move suggests Tehran is trying to keep diplomacy alive and stave off a major U.S. strike, according to Reuters.
