ANKARA, Turkey -- Two separate explosions in an industrial district of the Turkish capital killed at least 10 people on Thursday and injured dozens of others, reports and authorities said.
A powerful explosion collapsed two stories of a factory, leaving at least six people dead and injuring around 30 others, Interior Minister Besir Atalay said.
Hours later, another explosion shook an auto paint workshop in the same industrial zone, authorities said. Gov. Aladdin Yuksel of Ankara confirmed one dead in the second explosion.
The cause of the explosions was under investigation, but Ankara Mayor Melih Gokcek told CNN-Turk television that the factory blast was likely sparked by oxygen tanks. He did not give details.
Some workers were also believed to be trapped in the building where the second blast occurred, NTV television said. Search and rescue teams were trying to evacuate the trapped workers, it said.
Rescue officials also combed the rubble at the site of the first explosion for workers who may be trapped inside as well.
"Our hope is that there are no other deaths inside the ruins," Atalay told reporters at the scene of the first blast, which ripped off the building's glass-covered facade and shattered the windows of nearby buildings. Twisted metal and concrete slabs were strewn around the nearby area.
NTV news channel showed medics helping an injured man into an ambulance, while passers-by helped another lying on the pavement outside the four-story building.
A witness told NTV he saw dozens of people covered in blood lying on the ground before ambulances arrived at the scene.
Fethi Yasar, mayor for the area, said around half of the factory's 80 workers had escaped unharmed.
