Shirtless, rifle-waving Israeli soldiers have been disciplined for taking part in an “insane” army base concert where a pop star stripped to his sequined underwear and rode in the bucket of a bulldozer.

A group of Israel Defense Forces (IDF) reservists at an outpost in northern Israel were suspended over the raucous behaviour, which started when they were visited by Avihu Pinhasov for a morale-boosting performance.

Video footage of bare-chested Israeli troops waving their rifles around as they cheered on Mr Pinhasov is said to have bemused senior commanders, especially due to reports that large amounts of alcohol were consumed at the event.

Mr Pinhasov, who is virtually unknown outside of Israel but was once a Eurovision audition contestant, is filmed riding in the bucket of a bulldozer during the concert. He was dressed in unusual white overalls with goggles and carrying an Israeli flag.

In a series of video clips, he is seen leaping into the crowd and dancing, surrounded by cheering troops.

In one clip, soldiers try to tear off Mr Pinhasov’s clothing and he is subsequently seen dancing and singing in nothing but a pair of silver-sequined underwear briefs. He is also seen being carried on the shoulders of a soldier while spinning around in a circle.

He later throws himself on top of a group of reservists who attempt to help him crowd surf over other revellers, as the pop star continues to bellow into his microphone.

ICE, an Israeli news website, described the spectacle as “nothing short of insane”.

Israeli news outlet Walla! reported that the soldiers brandishing rifles in the video clips were suspended and sent home.

It is unclear which regiment or division was involved in the incident, though one Israeli media report described it as an alpine unit in the reserve forces.

Mr Pinhasov appears to have thoroughly enjoyed himself at the concert, posting on social media afterwards: “I saw lions in Hermon yesterday!” referring to Mount Hermon.

An IDF spokesman told Walla! that an investigation was launched, which found that the soldiers’ conduct fell short of army standards.

“Reservists who rioted and played with weapons were temporarily suspended from operational activity,” it said.

“The incident was investigated and a command conversation was held on the subject, during which it was made clear that the conduct was not in line with the values and orders of the IDF. Some of the fighters have since returned to their duties.

“The reserve service of the unit’s fighters who played with weapons was stopped immediately.”

This has not deterred Mr Pinhasov from vowing repeat performances at other army bases.

Quoted in ICE, Mr Pinhsov said: “If the army tells me to stop – I will not stop. I’m with the soldiers, I’ll do what they want.”

The Telegraph approached the IDF for comment.
