Security officials have found leaflets that were disseminated in Sheikh Zuwayed in Northern Sinai urging citizens to fight against the Armed Forces, the police, the judiciary, political parties and tribal leaders.
The police also found communications equipment, a color printer, a scanner and a small plane that operates by remote control, which could be used as an explosive.
A campaign began last week to restore security and stability in Sinai, following an attack by militants near the Rafah checkpoint earlier this month.
Israel handed over the bodies of the attackers to Egypt, saying Israeli forces had killed them after they crossed the border.
