A roadside bomb exploded in the restive northern part of the Sinai Peninsula, killing eight members of Egypt’s security forces, including an officer, while six others were wounded.
The troops were riding an armoured vehicle when the bomb went off in New Rafah, a town on the border with the Gaza Strip, said officials who spoke on condition of anonymity because they were not authorised to speak to the media.
The wounded, who suffered serious injuries, were transferred to a military hospital in the nearby Mediterranean city of el-Arish late on Thursday.
The armed group ISIL (ISIS) claimed responsibility for the attack in a statement on an ISIL-affiliated website.
In a similar attack last month, ISIL fighters ambushed a checkpoint in the town of Sheikh Zuweid, killing at least five troops and wounding at least six others.
Egypt has been battling armed groups in northern Sinai for years. Violence and instability there intensified after the 2013 military coup that removed Mohamed Morsi, an elected but divisive president, amid nationwide protests against his brief rule.
The fighters have carried out numerous attacks, mainly targeting Egyptian security forces, minority Christians, and those who they accuse of collaborating with the military and police.
