A sound of what seemed to be a massive explosion was heard all over Cairo on Wednesday. The loud blast shook windows in the southern neighborhood of Maadi, but was heard as far away as northern Cairo. The source of the loud noise, however, is yet to be determined.
The ministry of interior told MENA it was looking into the cause of the possible explosion in southern Cairo.
"We have received reports from several citizens who say they heard a loud explosion," in different parts of the city, Deputy Interior Minister Murad Mohsen told MENA, in statements broadcast on television.
"Security services have been sent to the various areas to investigate the reports," he said.
According to the German news agency the source of the sound was an explosion in a stone-pit near the Maadi district.
General Mohsen Mourad told Egypt’s Akhbar news website that the source of the sound was a plane which broke the sound barrier.
The collapse of a bridge in Maadi, the district where the sound is believed to have originated, has added to the confusion.
