Israel's prime minister harshly condemned the international community's nuclear deal with Iran yesterday while Western allies in the Persian Gulf were conspicuously quiet.
Elsewhere, many welcomed the agreement as an important first step toward curbing Iran's suspect nuclear programme.
Israel and Gulf countries led by Saudi Arabia have formed an unlikely alliance in their opposition to yesterday's deal, joined together by shared concerns about a nuclear-armed Iran.
Israeli Prime Minister Benjamin Netanyahu wasted little time in criticising the deal, calling it a "historic mistake" and saying he was not bound by it.
He said the world had become a "more dangerous place" as a result of the deal, and reiterated a threat to use military action against Iran if needed.
Under the deal, Iran will curb many of its nuclear activities for six months in exchange for limited and gradual relief from painful economic sanctions. The six-month period will give diplomats time to negotiate a more sweeping agreement.
The package includes freezing Iran's ability to enrich uranium at a maximum 5pc level, which is well below the threshold for weapons-grade material. International monitors will oversee Iran's compliance.
Israel fears Iran will trick the international community, the way North Korea did in its march towards building a nuclear bomb.
