Four Muslim Brotherhood members were arrested for photographing the navigation line of the Suez Canal and security checkpoints on the Port Said-Ismailia highway.
Security services have suspected a car driven by the four after noting that they were taking photos of the checkpoints, Port Said Security Director Ismail Ezzeddin said.
Photos of the Suez Canal navigation line and Al Salam Bridge were found stored on a cellphone in their possession, the security chief said.
They confessed that they were affiliated to the MB group and that the photos were taken to target these areas later, he added.
