TEHRAN (AFP) - The top public prosecutor in Tehran said on Tuesday he would seek the death penalty against three Iranians accused of being Israeli spies, the ISNA news agency reported. Saeed Mortazavi said the three had been "trained in Tel Aviv in assassinations, explosions, professional motorbike riding, and working with special cameras, computers and satellites." "The court will ask for the execution of the accused," he said, adding the group were arrested before carrying out any operations. Iran announced on Monday it had broken up a spy network linked to arch-enemy Israel's intelligence service Mossad, accusing it of gathering information on Iranian nuclear and military programmemes. News of the arrests came amid heightened tensions between the two enemy states over Tehran's atomic drive and just two days after Iran said it hanged an Iranian telecoms salesman convicted of spying for the Jewish state. "The first member of the network was arrested five to six months ago," Iran's ILNA news agency quoted Mortazavi as saying. The agency carried a picture of the prosecutor with the seized equipment including a satellite telephone, a GPS, a laptop and an oscilloscope. He said the network had been formed after "Mossad identified a former member of the Bajis (militia) and contacted him through an Israeli consulate in the region. "After training, this person had to attract other people and organise them for espionage," he said, adding that the three suspects had been trained by Mossad in four countries, including Iran's neighbours, as well as Israel. "They were trained by officers named Peter, Sally, Sami, Zaki and Khosrow," he said. On Saturday, Iran said it had executed telecoms salesman Ali Ashtari on November 17 for spying for Mossad for three years and warned that its intelligence war with Israel had "become more serious." Tehran does not recognise Israel and tensions have been exacerbated since the 2005 election of President Mahmoud Ahmadinejad, who has repeatedly said the Jewish state is doomed to vanish and branded the Holocaust a "myth". Iran insists its nuclear programmeme is only aimed at producing electricity and angrily points to Israel's widely believed status as the sole, if undeclared, nuclear armed state in the Middle East.
