JERUSALEM (AFP) - Israeli President Shimon Peres warned on Sunday that an attack on Iran is becoming increasingly likely, days before a report by the UN's nuclear watchdog on Iran's nuclear programme. "The possibility of a military attack against Iran is now closer to being applied than the application of a diplomatic option," Peres told the Israel Hayom daily. "We must stay calm and resist pressure so that we can consider every alternative," he added. "I don't think that any decision has already been made, but there is an impression that Iran is getting closer to nuclear weapons." His comments came after he warned in an interview aired by Israel's privately-owned Channel Two television on Saturday, that an attack on Iran was becoming "more and more likely." "The intelligence services of the different countries that are keeping an eye on (Iran) are worried and putting pressure on their leaders to warn that Iran is ready to obtain the nuclear weapon," he said. In recent days, speculation in Israel has grown about the possibility of an pre-emptive strike against Iranian nuclear facilities. On Wednesday, the Haaretz newspaper reported that Prime Minister Benjamin Netanyahu and Defence Minister Ehud Barak were seeking cabinet support for an attack. And the military last week carried out what Israeli media called a "ballistic missile" test, as well as a large-scale civil defence drill simulating the response to conventional and non-conventional missile attacks. Officials said both events were long-planned, but they drove talk here about whether Israel is ramping up plans for an attack. On Sunday, Haaretz reported that US officials had failed to secure a commitment from Israel that it would coordinate any attack plans with Washington. Citing unnamed US officials, Haaretz said US Defence Secretary Leon Panetta had used a recent visit to Israel to make clear Washington did not want to be surprised by any Israeli attack, but received only a vague response from Netanyahu and Barak.
