Singaporean Megat Shahdan Abdul Samad has appeared in a new propaganda video by terror group Islamic State in Iraq and Syria (ISIS).

The clip is believed to have surfaced on Dec. 29, 2017, according to The Straits Times.

Towards the end of the video, Shahdan is featured speaking in English, telling followers to strengthen themselves and "slay the enemies of Allah wherever you can find them".

He appears in the clip with two other men dressed in military fatigues and they can be seen executing three men by shooting them.

This is the first known video of a Singaporean participating in an execution for ISIS.

Video's release coincides with New Year

The 39-year-old Singaporean, who identifies himself as "Abu Uqayl", last appeared in a three-and-a-half-minute ISIS clip in September 2017.

This latest clip is over eight minutes long and has been shared in messaging groups and over social media.

The release of this new video has been timed to incite attacks at New Year celebrations, analysts believe.

Shahdan was a secret society member in Singapore with a string of drug and criminal convictions.

He went to the Middle East to work in 2014, where he was believed to have been radicalised.

He later made his way to Syria to join ISIS.
