French President Francois Hollande on Wednesday said he wanted "concrete acts" from Iran to prove it was not pursuing nuclear arms, after his first direct meeting with Israeli Prime Minister Benjamin Netanyahu.
Addressing a joint press conference with Netanyahu, whose aim during the two-day visit is to press for more pressure on Tehran, Hollande warned that Paris would back "other sanctions" if Tehran failed to convince on its contested nuclear programme.
"This is a threat which cannot be accepted by France," Hollande said.
"We have voted for many sanctions and are ready to vote others as long as necessary," the French leader said, underscoring that he wanted "proof that Iran has abandoned this drive."
Israel and Western nations say Iran’s nuclear programme is a front for a drive for a weapons capability.
Netanyahu hailed the "extremely important position" taken by Hollande.
Netanyahu has warned that a nuclear Iran would pose an existential threat to the Jewish state and has repeatedly refused to rule out military action, fuelling speculation that an attack was imminent.
But he then appeared to pull back, pushing the deadline until spring or even summer 2013, ostensibly to allow time for international sanctions to work.
The Israeli leader said in an interview Wednesday that the Arab world would be relieved if Israel struck at Iranian nuclear facilities.
He said in case of an attack, "five minutes later, contrary to what sceptics think, I believe there will be a great feeling of relief throughout the region."
"Iran is not popular in the Arab world, far from it," he said in comments reported in French in France's Paris Match weekly.
"And some neighbouring regimes and their citizens have well understood that a nuclear-armed Iran is a danger for them, not only for Israel," he said, without mentioning specific nations.
Hollande meanwhile urged Israel and the Palestinians to resume peace talks without any conditions, while criticising continued Israeli occupation.
"Only negotiations can lead to a definitive solution," he said. "These negotiations are hoped for and awaited."
He said the two countries had "divergences on occupation, which we want to see halted."
Netanyahu is hoping during the two-day trip "to build a good working relationship with the French leader," a source close to the Israeli leader told AFP.
Since taking office five months ago, Hollande has only spoken to Netanyahu by telephone but met Palestinian president Mahmud Abbas twice -- both times in Paris.
Netanyahu enjoyed close ties with Hollande's predecessor Nicolas Sarkozy who cast himself as a "friend of Israel" but there was a chill after Sarkozy reportedly called him a "liar" in November last year during a private conversation with US President Barack Obama.
Netanyahu was due to meet Prime Minister Jean-Marc Ayrault and Foreign Minister Laurent Fabius later in the day.
On Thursday, Netanyahu is to travel to Toulouse with Hollande to attend amemorial ceremony for three Jewish children and a teacher at the Ozar Hatorah Jewish school who were shot dead by an Islamist gunman who also killed soldiers of North African origin.
The Israeli Prime Minister also evoked rising anti-Semitism, which he said was a "threat for all the European people."
