Iran calls Obama's 10-year nuclear demand 'unacceptable'

Iran rejected on Tuesday as "unacceptable" U.S. President Barack Obama's demand that it freeze sensitive nuclear activities for at least 10 years but said it would continue talks on a deal, Iran's semi-official Fars news agency reported.

Iran laid out the position as the U.S. and Iranian foreign ministers met for a second day of negotiations and as Israeli Prime Minister Benjamin Netanyahu delivered a stinging critique of the agreement they are trying to hammer out.
