Egypt's airports will be on high alert ahead of 30 June when opposition protesters plan to demonstrate against President Mohamed Morsi, security officials say on Saturday.

"An emergency plan will be put in place from 28 June – 1 July," the head of EgyptAir security, General Magdy El-Yousri, tells reporters.

At the Cairo International Airport, security patrols will be increased, passengers will be thoroughly checked and new cameras will be installed "to monitor and confront any emergency," he details.

Civil Aviation Minister Wael El-Maadawy has been in talks for several days with airport and security officials as well as the heads of businesses affiliated with the EgyptAir holding company that runs the national carrier.

General Magdy Elwan, who heads the EgyptAir holding company confirmed that "from 28 June – 1 July there is a high alert."

In the provinces, security will be beefed up at airports and EgyptAir offices.

Security personnel will be given the necessary arms and equipment "to protect these vital establishments," an airport official said.

A signature-collecting campaign called Tamarod (Rebel in Arabic) first called for the anti-Morsi rally to coincide with the first anniversary of his taking office.

Tamarod rapidly picked up steam and organisers announced they collected their target 15 million signatures demanding that Morsi step down, which outnumbers the 13.2 that voted him into office for his four-year term.
