Twelve people were hurt Thursday in an explosion and fire at a chemical plant near Cairo International Airport, a source in the Egyptian security services told EFE.

The injured were taken to hospitals, the source said, speaking on condition of anonymity.

"Due to high temperatures, an explosion happened at a petrochemicals storage belonging to the Heliopolis for Chemical Industries," a spokesman for the military, Col. Tamer al-Rifai, said on social media.

Firefighters have brought the blaze under control, he said.

The civil aviation minister, Younis al-Masri, denied that the explosion occurred inside the airport and said that flights continued to land and depart without incident.
