One person was killed and 11 others, including four policemen, injured in an explosion in Egypt's restive North Sinai province.
A roadside bomb went off when an armoured vehicle passed by it in Al-Arish city late yesterday, killing a 19-year-old civilian, security officials said.
Security forces cordoned off the area and are investigating the incident.
Egypt's North Sinai has witnessed many violent attacks by militants since the January 2011 revolution that toppled the ex-president Hosni Mubarak.
The attacks targeting police and military increased after the ouster of Islamist ex-president Mohamed Morsi in 2013 by military following massive protests against his rule.
Over 700 security personnel have been reported killed since then.
The military has launched security campaigns in the area, arrested suspects and demolished houses that belong to terrorists, including those facilitating tunnels leading to the Gaza Strip.
