Egyptian security and health officials say a fire at a factory north of Cairo has killed five workers and injured four.

Officials say the fire at the starch and glucose factory in the Shubra el-Kheima district north of Cairo happened when a boiler exploded.

The officials, speaking on condition of anonymity because they were not authorized to speak to journalists, say they were able to control the fire before it spread.

Less than two weeks ago, a fire at a furniture factory east of Cairo killed 25 people and injured 22. Egyptian state-run media said that factory had not obtained a government safety certification.
