Authorities in Turkey are investigating after 17 people were killed in two separate explosions in the capital.
The blasts shook the same industrial area of Ankara hours apart on Thursday.
A possible malfunction in an oxygen tank is believed to have caused the first explosion, which partly collapsed two storeys of a factory. Rescue workers have so far pulled seven bodies from the rubble.
The second blast sparked a huge blaze which engulfed several workshops and raged throughout the night. Ten bodies have been recovered so far.
