EL-ARISH, Egypt — Security officials in Egypt say a suspected member of an al-Qaeda-inspired group has been killed by his own roadside bomb in the country’s restive Sinai Peninsula.

The officials say the terrorist’s father lost an arm in the blast Saturday. They say both men are members of Ansar Beit al-Maqdis, which has been blamed for some of the bloodiest attacks in Egypt in recent years. Their assaults increased dramatically after the overthrow of the Islamist President Mohammed Morsi last July.

The officials say the two were trying to plant the bomb on a road frequently used by the army. They spoke on condition of anonymity because they are not authorized to brief journalists.

The attempted attack comes as Egyptians will vote Monday and Tuesday in a presidential election.
