The attack on five army checkpoints along the Arish-Rafah road in North Sinai has left 22 dead, including 18 soldiers and four civilians, a medical source in North Sinai said Thursday in an update to the numbers declared hours earlier.
Eye-witnesses told Al-Masry Al-Youm that four vehicles with over 20 gunmen attacked the recently-erected checkpoints along the Arish-Rafah road with RPGs and mortars. The crossfire lasted over 20 minutes, the newspaper reported.
Army spokesperson Mohamed Samir had stated that 15 of the attackers were killed as the forces fired back.
The source said more than 30 others, inculdung civilians and troopers, were wounded.
There was no immediate claim of responsibility for the attack but militants who support Islamic State, the ultra-hardline group that controls parts of Iraq and Syria, have carried out similar operations in the Sinai Peninsula.
Egypt is gradually recovering from years of political turmoil following the ouster of autocrat Hosni Mubarak in 2011 and foreign investors are starting to return. But the biggest Arab state still faces security challenges on several fronts.
Sinai-based militants have killed hundreds of soldiers and police since the army toppled Mohamed Mursi of the Muslim Brotherhood — Egypt's first freely-elected president — in 2013 after mass protests against his rule.
That insurgency has spread to other parts of Egypt though bombing attacks in cities and towns are usually far less dramatic.
President Abdel Fattah al-Sisi, who has spearheaded an Arab initiative to create a joint military force to confront regional security challenges, says militants based next door in chaotic Libya also pose a threat to Egypt.
In January, Islamic State's Egypt wing, Sinai Province, claimed responsibility for a series of attacks that killed at least 30 people.
Then-army chief Sisi removed the Muslim Brotherhood from power in mid-2013 and mounted a fierce crackdown on the Islamist movement. Security forces killed hundreds in the streets and arrested thousands, neutralising what was once Egypt's most organised political group.
But Sinai Province and other militant organisation who are violently opposed to the US-backed government have proven resilient.
