Nuriye Savas (sitting C), mother of Muzaffer Savas, 28, who was killed in Tuesday's attack, mourns as she is accompanied by her sister, Ayse (sitting L), and her relatives during her son's funeral in Ankara May 23, 2007. Turkey's separatist Kurdistan Workers Party (PKK) denied on Wednesday carrying out a bomb attack which killed six people in Ankara, after Turkish officials said the attack bore the hallmarks of the group. Ankara's governor said earlier on Wednesday authorities had identified the remains of a suicide bomber who carried out the attack in Turkey's capital on Tuesday, and the type of explosives used pointed to Kurdish separatists.
