The son of the Lockerbie bomber has warned that Britain will be hit by a fresh wave of terrorism from Libya.
Khaled al-Megrahi said that Libyan fanatics stand ready to strike against other Western cities in the wake of the Manchester terror attack.
While security experts have warned that the country - which has been plunged into civil war in the wake of Colonel's Gaddafi death in 2011 - has become a fertile breeding ground for ISIS.
The chilling warning comes a week after Salman Abedi killed 22 innocent people and injured 119 more when he blew himself up at the end of a teen pop concert.
The son of Libyan parents, he is thought to have come back to Britain from Libya just days before the massacre.
Mr al-Megrahi, whose father Abdelbaset al-Megrahi was the only man ever convicted of the 1988 Lockerbie bombing, accused the West of abandoning the country leaving terror group ISIS to seize control of parts of it.
In a chilling warning from Tripoli, he said the Libyan capital is awash with young terror hopefuls like Abedi eager to die as 'martyrs'.
According to The Sunday Post he said: 'The militants will kill each other here and then come to each city in the west.
It is only a sea between us.
A lot of Libyans are hungry, have no money and no justice. If the West continues its stance you will see a lot of the militants coming to the UK.
The West knows what's happening in Libya but they only want to watch and see.
You make Libya like this. You will see a lot of terrorists in the UK and everywhere.
It was Manchester but tomorrow it will be some other place.
David Cameron led Britain into a coalition to carry out airstrikes on the north African country in the wake of the Arab Spring.
But the former Prime Minister has been widely criticised for failing to have a plan to rebuild the country after its longstanding dictator was ousted.
Chaos , bloodshed and a protracted civil war has ensued which has fuelled the refugee crisis and provided a fertile recruiting ground for terrorists.
Mr al-Megrahi, 32, called for the UK to resume airstrikes to restore order in Libya and rid the world of a rich recruiting ground for terrorists.
He said: 'It was easy for them to do it in 2011 and it would be easy to do it again.
This time they should arm the army and not arm the militias.
Professor Anthony Glees, director of the Centre for Security and Intelligence Studies at The University of Buckingham, told The Express: 'This is entirely credible.
We didn't realise that in place of Colonel Gaddafi a vacuum would be created that Islamists would seize.
'nyone travelling from there – and other countries – should be viewed with suspicion.
Prof Paul Rogers, a Middle East expert at the University of Bradford, said:
It's a terrifying mess. It's made it very easy for a brutal group like Isis to have a presence there.
In a devastating verdict, the Commons foreign affairs committee savaged Mr Cameron's judgment in rushing to war in Libya in 2011, saying the intervention was based on 'erroneous assumptions'.
The cross-party committee accused Mr Cameron of ignoring military chiefs and a lack of reliable intelligence to pursue an 'opportunistic policy of regime change' in Libya.
And it says he gave little thought to how Libya would fare following the removal of dictator Colonel Gaddafi, setting the scene for the country's descent into chaos.
Abdelbaset al-Megrahi, the only person convicted over the 1988 Lockerbie bombing above Scotland which killed 270 people.
He was freed from Scottish jail in 2009 on compassionate grounds because of cancer. He died in May 2012.
