"There is a security plan in place in tourist areas that will maintain stability in these areas," said ministry spokesman Hany Abdel Latif.
"We expected all these problems because we are in a war against terrorism," he said without elaborating.
Al Qaeda-inspired militants have targeted police and soldiers almost daily in the Sinai Peninsula since the army toppled Islamist President Mohamed Mursi in early July.
Gunmen killed a police officer and wounded another in the Suez Canal city of Port Said yesterday, security sources said. The police were guarding a customs office south of the city.
Political turmoil and bouts of violence have hammered the tourism industry, a traditional pillar of Egypt's economy and a main source of foreign currency, since the fall of former president Hosni Mubarak in 2011.
Militant attacks have multiplied since the military ousted Mr Mursi on July 3, raising concerns in the West that it is no longer safe to visit Egypt's pyramids, bazaars and beaches.
On Monday, suspected militants killed six Egyptian soldiers near the Suez Canal.
