Washington- Israel has denied a report that it spied on talks between Iran and the US over Iran's nuclear program.

A senior Israeli official told sources that the claims, reported in the Wall Street Journal, were "utterly false".

The journal said Israel wanted details of the talks in order to build a case against a nuclear deal with Iran.

Earlier this month, Israeli Prime Minister Benjamin Netanyahu told the US Congress that a deal being discussed could "pave Iran's path to the bomb".

The US, UK, France, Germany, Russia and China are seeking to reach agreement to curtail Iran's nuclear programme in exchange for sanctions relief.

They fear Iran wants to build a nuclear bomb - something Iran denies, insisting it is merely exercising its right to peaceful nuclear power.

The sides aim to reach a framework deal by the end of March.

According to Tuesday's report in the journal, Israel began eavesdropping on the talks last year and also acquired information from confidential briefings with US officials and diplomatic contacts in Europe.

The White House uncovered the operation, the report said, when US intelligence agencies spying on Israel intercepted messages among Israeli officials that could only have come from closed-door talks.

'False allegations'

US officials were particularly upset that Israel had sought to share the information with US lawmakers and others to build a case against the deal, the report added.

But a senior official in Mr Netanyahu's office told the BBC on Tuesday: "These allegations are utterly false.

"The state of Israel does not conduct espionage against the United States or Israel's other allies. The false allegations are clearly intended to undermine the strong ties between the United States and Israel and the security and intelligence relationship we share."

The report comes amid tense relations between the White House and Mr Netanyahu's government.

The Israeli prime minister angered Washington in his recent re-election campaign when he said he would not allow a Palestinian state if he was returned to office.

He later tempered his statement, saying he did want a two-state solution, but that "circumstances have to change".
