Iran will begin enriching uranium to 60% purity, higher than the program ever has before though still short of weapons grade, after an attack on its Natanz nuclear facility, an Iranian negotiator said Tuesday.
The announcement marks a significant escalation after the sabotage, suspected of having been carried out by Israel. It could result in further action by Israel, whose Prime Minister Benjamin Netanyahu has vowed never to allow Tehran to obtain a nuclear weapon, and further raise tensions across the Mideast.
