The Godfather-style gang war gripping two major cities - with brutal attacks caught on camera

It's like The Godfather, one reformed drug trafficker tells me.

The mythical gangster film centred on an organised crime dynasty locked in a transfer of power. Communities in Scotland currently have a front row seat to a new war of violence, torture, and taunts as feuding drug lords and notorious families grapple for control of Glasgow and Edinburgh.

There have been more than a dozen brutal attacks over the past six weeks - ranging from fire bombings to attacks on children and gun violence. Victims left for dead, businesses up in flames Gangsters have filmed themselves setting fire to buildings and homes connected to the associates and relatives of their bitter rivals.

The main aim, they boast, is to "exterminate" the opposition. The taunting footage, accompanied by the song Keep On Running by The Spencer Davis Group, has been plastered over social media as part of a deliberate game of goading.

A 12-year-old boy and 72-year-old woman were left for dead when teenagers wearing balaclavas burst into a home in north Glasgow. Garages and businesses have gone up in flames.

Shots were fired at an Edinburgh house. Signals are being sent of who wants control of Scotland's dark criminal underworld.

What's caused the gang war? The former director of the Scottish Crime and Drug Enforcement Agency, Graeme Pearson, explains how a "vacuum of leadership" is playing a part. Last October, Glasgow-based cocaine kingpin Jamie Stevenson, known as The Iceman, was jailed after orchestrating a £100m cocaine shipment stashed in banana boxes from South America.

The mob leader was one of Britain's most wanted, running his business like another on-screen criminal enterprise: The Sopranos. The 59-year-old fugitive went on the run before eventually being hunted and apprehended by police while out jogging in the Netherlands.

'Old scores to settle' But paranoia was running rife about how this notorious gangster could be brought down. Was there a grass? Was it one of their own? It further fuelled divisions and forced new alliances to be forged across Scotland's organised criminal networks.

It wasn't until The Iceman case came to court that it was revealed an encrypted messaging platform, known as EncroChat, had been infiltrated by law enforcement. It ultimately led to Stevenson pleading guilty.

Ex-senior drug enforcement officer Mr Pearson told Sky News: "It is a complex picture because you have got people who are in prison who still want to have influence outside and look after what was their business. "On the outside you've got wannabes who are coming forward, and they think this is an opportunity for them, and you have got others have old scores to settle that they could not settle when crime bosses were around."

He concluded: "All that mixes together - and the greed for the money that comes from drugs, and from the kudos that comes from being a 'main man', and you end up with competition, violence, and the kind of incidents we have seen over the past four to six weeks." New wave of violence 'barbaric' Glasgow man Mark Dempster is a former addict, dealer, and drug smuggler who is now an author and respected counsellor helping people quit drinking and drugs. He describes the "jostle for power" as not a new concept among Glasgow's high profile gangland families.

"There is always going to be someone new who wants to control the markets. It is like The Godfather.

There is no difference between Scotland, Albania, or India," he said. Mr Dempster suggests a shift in tactics in Glasgow and Edinburgh in recent weeks, with 12-year-olds being viciously attacked in the middle of the night.

"It is barbaric. When young people, children, get pulled into the cross fire.

It takes it to a different level. "At least with the old mafiosa they had an unwritten rule that no children, no other family members.

You would deal directly with the main people that were your opposition." Police Scotland is racing to get control of the situation, but declined to speak to Sky News about its ongoing operation. It has been suggested 100 officers are working on this case, with "arrests imminent".

But this is at the very sharp end of sophisticated criminal empires where the police are not feared, there are fierce vendettas and, clearly, power is up for grabs..
