A jihadist from the Islamic State apparently tried to film a video in which he swore allegiance to the terrorist group did not go as planned – after being interrupted several times by a screaming bird.

Images of what you think is the unidentified activist who records the clip have appeared.

The video was shared on Twitter by Elisabeth Kendall, senior researcher in Arabic at Pembroke College, Oxford.

She said the clip showed the leader of the Yemeni branch of the terrorist group.

We see the activist checking a piece of paper, apparently a script of what he has to say, before his voice is drowned by the bird.

It stops and tries again, but the bird makes a new attempt.

"A heroic bird drowns tirelessly in ISIS-Y's attempt to renew its allegiance to the caliph," tweeted Dr. Kendall.

"The weak memory of Leader adds to the misfortunes … These" catch "full-bodied were not included in the official video of this solemn event, published at the end of July."

In a subsequent tweet, she said that the clip had been published by Hidaya Media of al-Qaeda.

"#AQAP [al Qaeda in the Arabian Peninsula] probably found when they invaded the #ISIS camp at Qayfa #Yemen this summer.

"I traced the original ISIS-Y video without nonsense at 9/2017."

Al-Qaeda and the Islamic State were once closely linked, but the latter distanced itself in the years following the 2003 Iraq war and subsequent insurgency.

EI once held territory in Iraq and Syria, but militants lost the vast majority of the territory they previously controlled.
