ANKARA - A DNA report from a suicide bombing that killed 29 people in the Turkish capital Ankara last week suggests the main perpetrator was Turkish-born, not Syrian as initially stated by the government, a senior Turkish security official said on Tuesday.The report suggested the attack was carried out by Abdulbaki Somer, born in the eastern Turkish city of Van, the official said. Somer was the name given by the Kurdistan Freedom Hawks (TAK), a Kurdish militant group, when it claimed responsibility for the attack in a statement on its website on Friday."The DNA report has been published ... The bomber's DNA matches that of Abdulbaki's father. It looks like the bomber was Abdulbaki Somer, that's what the report is saying," the official told Reuters, speaking on condition of anonymity because the results of the investigation have not yet been made public.
