The Egyptian jihadist group Ansar Bayt Al-Maqdis on Sunday decapitated three people and shot a fourth on accusations of "collaborating" with Israel's Mossad spy agency and the Egyptian army, the Al-Ahram news website reported, citing a video published on online jihadist forums.

The group published a previous decapitation video of four others in August who they said had provided information that helped an Israeli drone strike kill three of the group's members in July.

The Aswat Masriya news website, founded by Reuters, reported that the video showed "confessions" of three persons and the shooting of another along with the destruction of his house.

The video also featured searches conducted by the group investigating passing cars and looking for "agents of the apostate army," Aswat Masriya said.

Sinai-based Ansar Bayt al-Maqdis has killed hundreds of Egyptian soldiers and police over the last year and beheaded several people in recent weeks, saying they were spies for Israeli intelligence.

It has carried out several similar beheadings of alleged “collaborators”, a method used by the “Islamic State” (IS or ISIS) group which has taken over large parts of Iraq and Syria.

On Thursday, the Egyptian Army eliminated a major terror leader in Ansar Bayt Al-Maqdis. 

Mohamed Abu Shatiya, who took part in the kidnapping of seven Egyptian soldiers in Sinai last year, died during fighting with the army south of Rafah, on the border with Gaza.

The group’s “IS copycat actions” have raised fears that it has links to IS.

IS has urged Ansar Bayt Al-Maqdis to continue their attacks against Egyptian security forces, noted Al-Ahram.

Sunday's video included footage of IS spokesman Mohamed Al-Adnany speaking about jihad and fighting infidels, said Aswat Masriya.
