TEHRAN (AFP) - Iran on Saturday hanged three men in public accused of involvement in the bombing of a Shia mosque that killed 25 people, an official said, branding them terrorists. The early morning executions were carried out near the mosque in southeastern Iran which was devastated by Thursdays bombing, said Hojatoeslam Ebrahim Hamidi, justice chief of Sistan-Baluchestan province. At least 125 people were also wounded in the powerful blast caused by a suicide bomber at the Amir al-Momenin mosque in the Sistan-Baluchestan provincial capital Zahedan during evening prayers. The terrorists Haji Noti Zehi, Gholam Rasoul Shahi Zehi and Zabihollah Naroui were hanged at 0130 GMT near the Amir al-Momenin Mosque in public, Hamidi told the official IRNA news agency. They confessed to illegally bringing explosives into Iran and giving them to the main person behind the bombing, he added. They were convicted of being mohareb (enemies of God) and 'corrupt on the earth and acting against national security, Hamidi said. He said the trio had been arrested before Thursdays bombing but had confessed that they had provided the explosives for the mosque bombing. They were tried and they had court-appointed legal representation, he said. The three men, he added, had also been charged with direct involvement in the bombing of a Revolutionary Guards bus in 2007 in which 13 people were killed, the bombing of Al-Ghadir Mosque in Zahedan in February this year which caused no casualties and some other bombings. President Mahmoud Ahmadinejad Saturday issued a statement advising alertness by Shia and Sunni brothers to neutralise the plots, and urging the authorities to quickly find, punish and uproot the evil hands of foreigners who were behind the bombing. He did not accuse any country in particular. The chief of the Iranian armed forces, General Hassan Firouzabadi, in comments carried Saturday on the state television website, accused Britain and Zionists of involvement in the bombing. We should not forget the role and the plot of the British who in the past 200 years tried to divide Sunnis and Shias, the general said. They should be careful not to play with lions tale, he added. The Iranian people and the armed forces are alert and will respond to any Zionist nonsense.
