Egyptian armed forces released late Thursday a video report with testimonies from injured soldiers and officers about what happened on Wednesday in North Sinai where there were heavy clashes between Egyptian armed forces and militants from Islamic State-affiliated Ansar Beit Al-Maqdis (ABM).

The official armed forces spokesperson Brigadier General Mohamed Samir published the 14-minute video on his official Facebook page Friday afternoon after it was initially released on the official Egyptian ministry of defence's YouTube channel late Thursday.  

The video included testimonies from army personnel and injured officers and soldiers who survived the terrorist attack and recounted the acts of other soldiers and officers who stood at checkpoints since early Wednesday morning.

Detailed graphic representations were included in video clips showing the attack by the militant group on 15 checkpoints in Al-Arish and Sheikh Zuweid on Wednesday.

The fight continued for several hours between the Egyptian security forces and the ABM militants in Sheikh Zuweid city until the evening when Egyptian air force strikes forced the militants to withdraw after suffering major losses.

The Egyptian army video also accused TV channels, including Qatar's Al-Jazeera TV, of aiding the militants.  

Battles between Islamist militants and the Egyptian army in North Sinai left at least 117 people dead including 17 army soldiers and 100 militants, according to official statements by the Egyptian armed forces.

Ansar Beit Al-Maqdis "ABM", which changed its name to Welayet Sinai (Sinai Province) after pledging allegiance to the Syria and Iraq based Islamic State group, often release videos -- mostly graphic as well in high quality -- showing its operations against Egyptian security forces and its beheadings of locals accused of collaborating with the Egyptian army.

The videos are usually released on social media websites such as YouTube and internet archives, as well pro-Islamic State forums and websites.

On Wednesday, the terrorist group released two statements on Twitter claiming responsibility for the attack, revealing that it involved suicide bombers.
