Twin explosions targeting Egyptian soldiers took place in North Sinai on Friday morning, state news agency MENA reported.
The bombs detonated near an armoured vehicle and a bus carrying soldiers near Rafah. No injuries have been reported.
The lawless Sinai Peninsula has witnessed a spike in attacks by Islamist militants since the ouster of Mohamed Morsi on 3 July.
In early September, the army launched a major operation in the sparsely populated province, arresting hundreds of suspected militants and destroying numerous arms caches.
Around 100 Islamist fighters and dozens of policemen, soldiers and civilians have died in the violence.
Violence has also spilled over into other parts of the country. In recent days, army and police launched joint raids on two towns where Islamist militants had killed policemen and torched churches.
