CAIRO - At least six Egyptian soldiers were killed in a series of attacks on Monday, October 07, in Cairo and Sinai, following a bloody day of protests in which 53 protesters were killed across Egypt.
"Unidentified people opened fire on a satellite receiver station in the neighborhood of Maadi in Cairo," the Ministry of Interior said in a statement cited by Reuters.
Security sources said assailants fired two rocket-propelled grenades at the site of the attack in which two people were injured.
The attacks started at Monday dawn when gunmen killed five Egyptian soldiers, including a lieutenant officer, as they sat in a car by a checkpoint near the Suez Canal city of Ismailia.
Another attack occurred when a car exploded outside a security building in a southern Sinai town.
Away from Sinai, the dawn attack on the earth station in the suburb of Maadi in Cairo caused only minor damage to one of the giant satellite dishes in the complex.
Monday's attacks came just one day after at least 50 people were killed in clashes between security forces and supporters of deposed former President Mohamed Morsi.
The deaths occurred when protesters tried to enter the iconic Tahrir Square, the rallying point for the popular uprising that toppled autocrat Hosni Mubarak in 2011, security sources said.
The interior ministry described the clashes as an attempt by the Muslim Brotherhood to "ruin the celebrations and cause friction with the masses".
It said in a statement 30 of the 33 dead had been killed in the Cairo and Giza governorates and 423 people had been arrested. Scores of people were reported wounded.
Four people were also killed last Friday when protesters tried to reach Tahrir Square.
Following a bloody Sunday, traffic flowed freely in the center of Cairo where bloody clashes took place.
Yet, the attacks in Cairo and Sinai were expected to do further damage to Egypt's vital tourism industry.
"It suggests that Sinai groups are infiltrating in greater numbers in to northern Egypt," David Hartwell, a Middle East analyst at IHS Jane's, told Reuters.
"Either these groups are expanding out of Sinai, he said, "or the capabilities that they have is being used by other groups that may or not be affiliated with the Brotherhood," he added.
Political tensions have gripped Egypt and hammered the economy since the army ousted Morsi in July, installed an interim government and presented a political roadmap it promised would bring fair elections.
Authorities have cracked down hard on the Brotherhood, which won every election since Mubarak's fall.
The Brotherhood accuses the military of staging a coup and sabotaging Egypt's democracy by removing Morsi, the country's first freely-elected president.
