Television footage of the fire showed guests at the hotel using bedsheets to climb down from windows.

A survivor told a local TV station that guests were sleeping when the fire broke out.

Chief Fire Officer Tehseen Siddiqui said although the blaze was not very intense and was contained early, smoke continued to circulate inside the hotel because the air conditioning system remained active. He said there was no exhaust system inside the hotel and "most people suffocated to death."
