It is the third in a string of recent terrorist incidents in Istanbul. On January 1, police subdued a man after he threw grenades and fired a weapon at officers near the prime minister's offices. And on Tuesday, a suicide bomber killed a police officer and wounded another in tourist district.
A leftist group first claimed responsibility for both of those incidents, but has now withdrawn its claim about the suicide bombing.
Some Turkish media have said the bomber was a Russian citizen of Chechen origin. Dogan said that no one has claimed responsibility for the bomb found today.
The incidents in Istanbul as well as the al-Qaida linked terrorist attacks that left 30 dead in France this week have left Turkey on edge. Today, the state-run Anadolu Agency said that Turkish Prime Minister Ahmet Davutoglu would join European leaders at a unity rally in Paris tomorrow.
