A masked pro-Palestinian activist has claimed responsibility for a firebomb attack on an Australian weapons manufacturer and warned more will follow until ‘every colony’ is destroyed. 

The mysterious individual made the chilling threat in a video while sitting at a desk with Aboriginal and Torres Strait Islander flags, while a Palestinian flag hung in the background.

The man claimed he was sharing an ‘anonymous communique’ on behalf of the ‘cell that torched three cars’ at Lovitt Technologies Australia, in Melbourne, on July 5.

The company supplies parts to the F-35 joint strike fighter program, a global initiative to help allied countries build fighter jets – including Israel.

Behind a black mask, the man claimed his group believes ‘every worker’ at Lovitt Technologies is ‘complicit’ in the ‘genocide’ occurring in Gaza.

‘We will decide your fate, as you have decided the fate of millions,’ he said.

‘For the past few months we have been closely watching you. We have your addresses.

‘All the information we have about you will be distributed to our underground networks.

‘Stop arming Israel or else.’

The man then warned the attack on July 5 was ‘not an accident or thoughtless act of vandalism’.

‘If you continue making weapons components of any kind there will be consequences. Consider this a warning,’ he said.

The video included detailed information on how to use firestarters to torch vehicles with the figure even demonstrating how to light one. 

‘Be mindful of fingerprints and DNA,’ he said.

As the video came to an end, the masked figure called for ‘death to Israel, death to Australia, death to America’.

‘Every colony will burn,’ he said.

‘We are behind the enemy lines of this genocide.

Earlier this month, three cars were set alight at Lovitt Technologies Australia (pictured), which supplies parts to the F-35 joint strike fighter program

‘It is our duty to attack the belly of this colonialist imperialist beast at every opportunity.’

Victoria Police are aware of the video and are investigating the attack. 

The Australian Jewish Association CEO Robert Gregory said the video was sent to the organisation on Sunday night ‘by a concerned member of the Jewish community’.

‘This is a deeply troubling escalation and a clear incitement to domestic terrorism,’ Mr Gregory told Daily Mail Australia. 

‘Australian businesses and their employees are being threatened. Authorities must act urgently, before someone is seriously harmed or killed. 

‘These sorts of terrorist threats to violence and intimidation should not be imported to Australia. 

‘Hateful chants are heard at anti-Israel protests each week and now it seems people are starting to act on them.’

The attack on July 5 saw five people access Lovitt Technologies Australia about 3.55am and set three cars alight.

The masked man only claimed responsibility for the July 5 attack and has not been linked to other incidents

One vehicle was destroyed and two sustained ‘moderate damage’, Victoria Police said.

The group also used red spray paint to vandalise a building wall. 

Officers are working with the Counter Terrorism Command to investigate the incident.

Daily Mail Australia has contacted Lovitt Technologies Australia for comment. 

The attack against Lovitt has not been linked to any other recent events in Melbourne and the video didn’t mention any other prior attacks.

Those incidents include the burning of an East Melbourne Synagogue on July 4.

A 34-year-old man is accused of arson after entering the synagogue grounds on Albert Street about 8pm.

He allegedly poured a flammable liquid on the front door and ignited it before fleeing on foot.

About 20 worshippers, including children, were inside having dinner and had to flee the burning building.

No injuries were reported. Firefighters quickly contained the fire, which prevented further damage.

That same night, Israeli-owned Miznon eatery was mobbed by 20 protesters on Hardware Lane, in the CBD.

The aggressive group hurled chairs, food and glassware at the venue while chanting ‘Death to the IDF (Israel Defense Forces)’.

Some members of the protest separated from the group and began throwing traffic bollards at passing cars while yelling profanities. 

Miznon diners screamed and turned furniture while attempting to escape the chaos while protesters clashed with dozens of police.

Three people were charged with assault, riotous behaviour and criminal damage following the incident.
