A armed group in Egypt has released a video showing what it claims is footage of an attack on the army in Sinai last month in which at least 30 soldiers were killed.

The group, formerly known as Ansar Beit al-Maqdis, says in the video that it now swears allegiance to the Islamic State in Iraq and the Levant (ISIL) and has renamed itself Wilayat Sinai.

Wilayat Sinai said in the video that it had taken up arms in response to the army's campaign to forcibly transfer people from the peninsula.

Al Jazeera cannot independently verify the video's authenticity,
