There are no reports of any deaths.
A massive explosion has occurred in the vicinity of Cairo International Airport.
A number of local tweets poured in with users claiming to have heard a loud explosion followed by the sounds of ambulances.
Egyptian firefighters battled flames that erupted after an explosion at a chemicals factory outside Cairo's main airport on Thursday, with a dozen people reported injured in a blast an army spokesman said was caused by high temperatures.More news: Pakistan police arrest Sharif's supporters to 'avoid violence'

The minister of civil aviation, Younis al-Masri, said air traffic at the airport was unaffected by the explosion, which could be heard across the area.
The blast is believed to have been the result of two fuel storage tanks, owned by a petrochemical company, catching fire and exploding outside the airport perimeter. In February 2015 authorities discovered bombs planted at the Cairo International Airport on the same day that a blast killed a man in Egypt's second city of Alexandria.
Security measures will surely be increased at the airport.
