25 Egyptian workers were killed and 22 others injured in a furniture factory fire in Obour, Egypt's health ministry spokesperson Hossam Abdel-Ghaffar told Ahram Online on Tuesday. 

The fire took place in a three-story furniture factory based in an industrial zone in the city of Obour in Qalyubia governorate, northeast of Cairo.

A security official told Ahram Arabic news website earlier that the fire erupted due to the explosion of a gas tank that workers were delivering inside the factory.

He also added that the fire quickly spread due to the materials and wooden merchandise inside the factory. 

A statement released by the Ministry of Interior stated the fire had been completely contained by 23 firefighting trucks. 

According to the ministry, after the fire started it spread to the rest of the factory's floors during the workers' morning shift.

Several factories have evacuated their workers after fears that the fire might spread, a civil defense official in Qalyubia governorate told Ahram Arabic news website earlier.
