Egypt says security forces killed 14 militants while pursuing attackers behind an assault on a police checkpoint in northern Sinai that authorities said left eight policemen dead.
The Islamic State group had claimed responsibility for Wednesday's attack near the city of el-Arish.
Egyptian security officials initially said as many as 10 policemen died in the attack but the discrepancy in the accounts could not be reconciled. The area is off limits to reporters.
The Interior Ministry says that while pursuing the attackers, security forces located a group of insurgents hiding inside a deserted house in the city. A shootout ensued, killing 14 militants who had automatic rifles, bombs and explosive belts in the possession.
Egypt has battled Islamic militants for years in northern Sinai, where the ISIS affiliate is based.
