At least 19 people were killed and 69 were injured today when an explosion ripped through an Istanbul building.
The building in the industrial district of Davutpasa housed more than 130 offices and workshops, including an illegal fireworks factory, police said
The explosion originated with a fire on the building's fourth floor.
There were fears that a bomb might be to blame. Various radical groups ranging from Kurdish separatists to far-left militants operate in Turkey.
Six people were killed and dozens injured in a blast in the southeast Turkish city of Diyarbakir earlier this month. That attack was blamed on the outlawed Kurdistan Workers Party.
