(AINA) -- The Turkish news site Radikal is reporting that Turkish prosecutors have released 11 of the 12 Al-Qaeda suspects who were arrested in Adana with possession of two kilograms of Sarin gas (AINA 9-14-2013). According to Radikal, the prosecutor in Adana said the police announced that the Sarin gas was determined to be anti-freeze. But chemical engineers who were consulted by Taraf newspaper said an expert cannot mistake anti-freeze for Sarin, as these are entirely different substances.
