Israel's prime minister says each day that passes brings greater Western concessions toward Iran in talks over its nuclear program.

Benjamin Netanyahu said Sunday the progressing talks in Vienna do not represent a "breakthrough but rather a breakdown." Western diplomats are trying to reach a deal before an extended July 7 target date. Any deal would result in an end to longstanding sanctions against Iran.

Israel has been a vocal opponent of loosening sanctions in return for curbs on Iran's nuclear program, saying this would just lead to a bomb and aid the Islamic Republic in expanding its network of global terrorism.

Netanyahu assailed a preliminary deal reached earlier this year. He says the looming accord is even worse than the one that previously allowed North Korea to go nuclear.
