BAKU  - Two powerful explosions at a detergent factory in Azerbaijan’s second-largest city of Sumgayit on Monday killed six people and left seven more injured, police told local media. Firefighters and emergencies ministry helicopters were dispatched to the scene in an attempt to extinguish flames in the industrial Caspian Sea coast city. It was not immediately clear what caused the explosions. “So far it is impossible to say anything concrete. Efforts to extinguish the fire are continuing,” Sumgayit’s local chief executive Eldar Azizov told journalists.
