Israeli Prime Minister Benjamin Netanyahu on Wednesday expressed concern ahead of the next round of talks between Iran and the international community over Tehran's controversial nuclear program.

"This model of a country talking, but at the same time developing nuclear weapons; threatening and at the same time developing nuclear weapons and threatening the use of nuclear weapons, we cannot allow this to happen in Iran," a statement from Netanyahu's office cited him as saying.
