The separatist Kurdistan Workers Party (PKK) denied responsibility for the May 22 bomb attack that killed six and wounded up to 100 in the busy Ankara shopping district of Ulus. "We have no connection with the attack," the PKK said in a statement posted on the Firat news agency website, which has ties to the guerrillas. Turkish authorities initially said a suicide bomber carried out the attack, but that the use of A-4 plastic explosives points to the PKK. The PKK has used the explosive in the past, but typically does not carry out suicide bombings. (Hurriyet, Reuters, May 24)
