An explosion tore through the main square in Istanbul, Turkey, injuring more than 30 people today. Gul Tuysuz reports the blast is blamed on a suicide bomber 10.

Five of the injured are in critical condition, according to Istanbul's police chief. The suicide bomber was killed in the attack. Although no groups have officially claimed responsibility, analysts 11 speculated on Turkish TV that the Kurdistan Workers' Party (PKK) organized the attack. A unilateral ceasefire imposed by the PKK ended on Saturday. Other analysts suspected that al-Qaeda was responsible for the attack. Turkey detained dozens of suspected members in raids across the country last week. And the suicide bombing bore similarities to the al-Qaeda-related attacks, which killed 30 people outside the British consulate 12 in Istanbul in 2003. For NPR News, Gul Tuysuz in Trabzon.
