Forty eight hours after a gas explosion in a Lahore factory, rescue workers pull a survivor out from the rubble.
Dozens of labourers, mostly aged between 14 and 23, were trapped inside when the building collapsed on Monday.
While one survivor was pulled out alive, others were less fortunate.
The death toll from the explosion has risen to 21.
Emergency crews continue to search for survivors amidst the rubble of the factory, which had 62 people inside when the blast occurred.
The incident will raise fresh questions about Pakistan's industrial safety, with critics highlighting weak and poorly enforced building regulations.
