Istanbul, Turkey (CNN) -- Turkish authorities reinforced police presence Monday around Istanbul's central Taksim Square, a day after a bomber detonated explosives there, killing himself and wounding 32 people.
"It's tense," said an owner of a nearby café who asked not to be identified. His business is but one of the hundreds of bars and restaurants around Taksim, in what is the most congested entertainment district in Turkey's largest city.
Turkish authorities have so far avoided identifying the dead bomber or any organized group they suspect may have been behind the attack. They have also played down the fact that Sunday's strike appeared to be a suicide bombing.
Meanwhile, in a phone interview with CNN, a spokesman for the Kurdistan Workers Party, or PKK, denied responsibility for the attack.
"Some circles are pointing to our movement as the ones who are responsible for this. This is not the reality," said PKK spokesman Roj Qandil, speaking by telephone from Northern Iraq where the rebel group's leadership is based. "We do not have any connection whatsoever with this action".
