Iran arrested four people who it said were intent on sabotaging facilities in its nuclear program, the President of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi said Sunday. \"Some time ago, a number of people were arrested in one of the nuclear facilities when they were involved in planning activities,\" Salehi was quoted by Iranian local media as saying. Salehi added that the four were still being questioned. \"Some countries will not stay silent as they are not interested in settlement of Iran\'s nuclear issues. In the meantime, through acts of sabotage they will try to create obstacles in the way of the resolution of the Iranian issue,\" Salehi added.
