Cairo: Four Egyptian soldiers where killed by a roadside bomb on Thursday in the Sinai Peninsula, where the army is battling an Islamist insurgency, the military said.
One officer and three soldiers died in the attack on their vehicle near the border town of Rafah, a military spokesman said on his Facebook page.
The attack came a few days after seven soldiers died in a jihadist attack on a checkpoint.
Militants loyal to the Islamic State group have killed hundreds of policemen and soldiers since the army overthrew Islamist president Mohamed Morsi in 2013.
The military says it has killed more than 1,000 militants in Sinai, which borders Israel and the Palestinian Gaza Strip.
