Turkish police have detained for questioning eight people with alleged links to Kurdish rebels following bomb attacks against two small hotels in Istanbul and a liquefied petroleum gas plant, police officials said Wednesday. A previously unknown Kurdish group claimed responsibility for the pre-dawn bomb attacks Tuesday that killed two people and wounded 11 others. An al-Qaida-linked group also claimed responsibility in a statement posted on a Web site, but Turkish authorities cast doubt on that claim, saying Kurdish separatists were suspected.
