ANKARA — Four former senior Turkish prosecutors and an ex-military commander went on trial Thursday over the interception last year of an alleged consignment of arms bound for Syria, with the court immediately imposing a secrecy order on the hugely controversial case. The case goes to the heart of claims — repeated on occasion by the West but denied by Turkey — that Ankara has worked far too closely with Islamist rebels in the hope of ousting Syrian President Bashar Al-Assad. The five, who were arrested earlier this year, are charged with seeking to overthrow the government and revealing state security information. They could face life in prison if found guilty. The trial opened at a criminal court within Turkey's Supreme Court in Ankara under heavy security, with the judge immediately imposing the secrecy order, the official Anatolia news agency reported. The order means the trial will be held behind closed doors and its proceedings with not be made public. — AFP
