Karachi: A Pakistani government official says authorities have buried 17 bodies that were never claimed after a factory fire killed 259 workers five months ago.

Ghanwar Leghari says the bodies were buried on Sunday, fulfilling a court order issued in the southern city of Karachi.

He says authorities have been trying to ascertain the identities of the victims through DNA testing. If they eventually can identify the victims through matching DNA, the bodies will be exhumed and handed over to relatives.

The factory caught fire on September 11, 2012 in Karachi.

The lack of proper fire safety systems in the factory was blamed for the high death toll.
