Egypt's official news agency says a roadside bomb hit an armored vehicle in northern Sinai, killing three soldiers.

MENA says the attack was carried out by Islamic extremists early Monday near the border town of Rafah. The team in the armored vehicle was searching for explosives.

Militant attacks, mainly targeting Egyptian security forces, have spiked since the 2013 military overthrow of Islamist President Mohammed Morsi following massive protests against his rule.

Most of the largest attacks have been carried out in the northern Sinai Peninsula and claimed by a local affiliate of the Islamic State group. At least 14 people, mostly soldiers, were killed in a wave of attacks in northern Sinai last week.
