Iran on Tuesday accused arch-rival Israel of attempting to poison the mood against its moderate president-elect Hassan Rowhani, who has raised hope to end a dispute over Tehran's nuclear ambitions.

Israeli Prime Minister Benjamin Netanyahu on Sunday called Rowhani "a wolf in sheep's clothing" who would "smile and build a bomb".

Iran's foreign ministry spokesman Abbas Araqchi, speaking to reporters on Tuesday, said Netanyahu was "angry" that Rowhani's June election had created "a positive atmosphere in the international community".

Netanyahu's remarks, he said, "is a sign of his regime's interference in Iran's relations with other countries, and a proof of its destructive role and attempt in damaging those relations".

Rowhani, an ex-nuclear negotiator who has held top state positions since the 1979 inception of the Islamic republic, is to take office from President Mahmoud Ahmadinejad on August 3.

Tensions between regional arch-foes Iran and Israel hit a strident high during Ahmadinejad's eight-year presidency, marked by his repeated controversial remarks regarding the Jewish state, including the denial of the Holocaust -- as Tehran dramatically expanded its nuclear programme.

Iran says it seeks peaceful nuclear applications, rejecting Western suspicions that the programme is aimed at military objectives, and brushing aside military threats by the United States and Israel against its work.

Netanyahu on Sunday renewed his threat to take unilateral military action, saying that Tehran's nuclear conduct was unlikely to change under Rowhani.

Iran in engaged in long-running but so-far fruitless negotiations with world powers aimed at resolving the nuclear standoff diplomatically.

Rowhani, 64, has promised to offer more transparency to resolve the nuclear issue, hoping to lift the sanctions which have left Iran's ailing economy in tatters.

Final decisions on Iran's nuclear drive rest with supreme leader Ayatollah Ali Khamenei.

EU's Ashton urges quick resumption of Iran nuclear talks
Brussels (AFP) July 16, 2013 - European Union foreign policy chief Catherine Ashton on Tuesday called for the resumption "as soon as possible" of talks between global powers and Iran on its contested nuclear programme.

Ashton hosted talks between political directors from the so-called P5+1 group that has been negotiating with Iran and which is made up of the five permanent UN Security Council members Britain, China, France, Rusia and the United States plus Germany.

"We met to consider our position and to look at how best we can move forward in trying to find a diplomatic solution to the Iranian nuclear issue," Ashton said in a video statement.

"Of course we wait now for the team to be appointed by Iran. We very much hope that will be soon and we look forward to meeting with them as soon as possible," she said.

It was the first such meeting since Hassan Rowhani was declared Iran's new president in June.

Western powers believe the programme is being used to develop an atomic bomb, but Iran insists it is for peaceful purposes.

Ashton met Iran's top nuclear negotiator Saeed Jalili in Istanbul in May for talks he described as "long and useful" that followed fruitless discussions the previous month in Almaty, Kazakhstan.

Iran's moderate president-elect vowed in June to implement a policy of "constructive interaction" with world powers to build trust and diffuse tensions, exacerbated over Tehran's nuclear ambitions.

"Moderation in foreign policy means neither surrender nor confrontation but constructive and efficacious interaction with the world," Rowhani said in his first live televised remarks since his election on June 14.

"In moderation, a balance must be achieved between realism and idealism," he said.

Iran is at odds with world powers both over its nuclear activities and support for the embattled regime of Syrian President Bashar al-Assad.

Rowhani did not mention either issue directly but said he would move to build trust and ease tensions after taking office on August 3.
