BERLIN, Aug 26 (Reuters) - Despite the murders of four of her colleagues for their reporting, Russian journalist Elena Kostyuchenko never considered she had been poisoned when she fell ill on a train to Berlin. But when I found myself in Europe I totally forgot all these security measures." Her symptoms started with disorientation and stomach ache on the train journey from Munich to Berlin and persisted for several weeks. A former Chechen rebel died in Berlin in what a German court said was a Russian state assassination. She was one of three Russian independent woman journalists who were apparently poisoned while abroad in a similar period.
