TEHRAN (Agencies) - Iran's President Mahmoud Ahmadinejad on Sunday told his visiting Syrian counterpart and staunch regional ally Bashar al-Assad that Tehran is serious about finding a practical solution to the nuclear crisis. "We are serious in talks and we want the talks to be based on the law so it will bear practical results. We hope that other sides are serious too," Ahmadinejad told Assad in remarks broadcast live on state-run television. According to CNN, Ahmadinejad said that diplomacy is the only way out of his country's standoff with the West over the programme and insisted he was serious about negotiations. On Saturday evening Ahmadinejad was quoted as telling his Syrian counterpart that Tehran "will not give an inch on its nuclear rights." His comments coincide with this weekend's US deadline for Iran to respond to an international package of incentives for it to freeze its drive to enrich uranium amid warnings of new sanctions if it does not. The Syrian leader's visit follows a trip to Paris a month ago during which French President Nicolas Sarkozy urged Syria to "persuade Iran" to prove that it is not seeking nuclear weapons. "When we were in France we told them about the Syrian position on Iran's nuclear issue but they asked us if we have details of the Iranian programme," Assad said on Sunday in Arabic through a translator. "In this trip we got details, so in future if we are asked again we know Iran's position." "In case he hasn't noticed, we are trying to talk with them," White House Press Secretary Dana Perino said from Kennebunkport, Maine. "The door is open, they just need to step through it by suspending their enrichment of uranium." "I am not mediating and I don't carry any message from any Western country," Assad told reporters before returning to Damascus. Meanwhile Israeli Foreign Minister Tzipi Livni, a contender to become prime minister, urged the international community to act quickly on new sanctions against Iran, in comments broadcast Sunday by CNN television. "It is clear that Iran doesn't pay attention to talks, and this is a clear message to the international community to continue with real and effective sanctions," said Livni. "We need to understand that we need to act today in terms of sanctions. Sanctions can be effective, as long as the Iranians and the entire world understand that all the options are on the table." Iran has so far been slapped by three sets of United Nations Security Council resolutions demanding that it halt uranium enrichment. This process to produce fuel for nuclear power plants can also be used to make the fissile core of an atomic bomb. The West fears Iran's atomic programme is a cover for making nuclear weapons, a charge vehemently denied by Tehran which says it needs nuclear power to produce electricity for a growing population. The United States and its ally Israel are leading the pressure on Iran and have not ruled out military action. Israel, which considers Iran its greatest threat, is widely believed to be the only nuclear armed state in the Middle East although it has a policy of neither confirming or denying it has a nuclear arsenal. It also does not allow international inspections.
