Iran nuclear talks to resume with world powers after five-month hiatus

Expectations of salvaging 2015 deal low amid fears Iran is covertly boosting nuclear programme

Talks between world powers and Iran on salvaging the 2015 nuclear deal will resume in Vienna on Monday after a five-month hiatus, but expectations of a breakthrough are low.

The talks could liberate Iran from hundreds of western economic sanctions or lead to a tightening of the economic noose and the intensified threat of military attacks by Israel.
