Eight policemen were killed and three others injured after militants attacked a security checkpoint in Egypt’s New Valley governorate, near the Western Desert, the interior ministry said late on Monday.
The attack on the Naqb checkpoint took place some 80 kilometers away from the provincial capital of Al-Kharga, and more than 600 kilometres southwest of Cairo.
State TV said earlier that the attack took place at 8:15pm Cairo Local Time.
Two of the assailants were killed as security forces responded to the assault, the ministry added.
There was no immediate claim of responsibility.
Egypt is battling an Islamist insurgency based in parts of North Sinai, which has occasionally hit mainland cities.
The militancy has mainly targeted police and troops, killing hundreds in the past three years. The army has also killed hundreds of militants in its campaign to root out the insurgency in the border region.
This is not the first time New Valley (Al-Wadi Al-Gaded) governorate has been targeted by militancy.
In July 2014, militants firing machineguns and rocket-propelled grenades killed 21 soldiers in an attack on a border checkpoint in the Farafra Oasis.
