Jan 11 (DPA -NT) - Two Turkish offices in Cologne and Bochum were damaged in attacks during the night, police said Thursday. Unknown attackers threw a paving stone through the window of a Turkish cultural organisation and followed that with a Molotov cocktail which set the premises alight. In the Ruhr city of Bochum, a Turkish business was set on fire. A message several pages long handwritten in Turkish which was found at the scene in Cologne indicated that extreme left-wing Turkish circles were responsible, a police spokeswoman said. No on was injured in the attacks. The fire-bomb tactic has been adopted by other left-wing Turk groups, who have stepped up their attacks since the beginning of the year. A flag of the Turkish Dev-Sol underground movement, which is banned in Germany, was found near a bank which was attacked on January 5. The attacks this year are thought to have been in protest at conditions for political prisoners in Turkish prisons. A total of 29 prison officers were for a time held hostage when prisoners in Turkish jails revolted last week. The revolt ended on Tuesday. dpa ur /AA1234/111012 Jan 96 nnnn
