The Ministry Egyptian Interior Sunday revised upwards the attack that targeted the balance sheet the day before police in the Sinai Peninsula, adding that 15 policemen were killed in the attack claimed by the Islamic State group (EI ).
A first assessment was given Saturday reported the death of 13 policemen at the checkpoint near Al-Arish, capital of North Sinai.
The ministry had spoken of a mortar attack, but the Egyptian branch of the IU claimed to have used a suicide bomber aboard a car bomb before its fighters launched the attack.
Three officers were among the victims, the ministry said.
This is the deadliest attack for several months in the Sinai. In this desert region of northeastern Egypt, the Egyptian branch of the IU regularly conducts attacks against the police and army since the military ousted the Islamist President Mohamed Morsi in 2013.
Five attackers were also killed in clashes that took place after the attack near the checkpoint, said Saturday the heads of security services.
Authorities said hundreds of police and soldiers have been killed since 2013 in jihadist attacks, mainly in the northern Sinai.
These attacks are almost always claimed by the Egyptian branch of the IU, "Sinai Province".
Jihadists of EI had also claimed responsibility for the crash of a plane of Russian tourists which crashed on October 31 in Sinai, killing all 224 people aboard.
