The death toll in a fire which engulfed a shopping centre in Pakistan has climbed to 67, police have confirmed.

Police say 77 people are currently reported as missing by their families following the fire at Gul Plaza, in Pakistan's largest city Karachi, on Saturday evening.

But the scale of the damage following the blaze - which took more than 24 hours to put out - has slowed rescue efforts, as authorities comb the remains of the 6,500sq m (70,000 sq ft) complex.

While some of the bodies found are only partial remains, authorities had been able to count 67 skulls, the deputy commissioner of police told the BBC. The process to identify the bodies continues, with 15 people identified so far.

Gul Plaza had housed some 1,200 shops, spread across multiple floors. It is wedding season in Karachi, often a particularly busy time of year for shoppers.
