Boris Johnson today announced £9million of aid for Libya as he pledged Britain's support to stop the war-torn country becoming a 'fertile ground for terrorists'.

The Foreign Secretary said the extra cash will help fund the removal of improvised explosives and landmines and pay for food and medicine for Libyans.

He said the measures will help in the battle to bring stability to the country which has been in the throws of civil war since Muammar Gadaffi's death in 2011.

It comes after the Libyan Prime Minister warned Europe is at growing risk from ISIS terrorists unless it does more to help the country stem the massive tide of immigrants.

Faiez Serraj said murderous jihadis are among the tens of thousands of migrants passing through his country's borders determined to head for Europe.

His stark warning comes after terror attacks in Barcelona and Finland last week left 17 dead. 'That's why it is so important that we work with the Libyan government and our partners to help bring stability to Libya, stopping it from becoming a fertile ground for terrorists, gun runners and people traffickers in close proximity to Europe.

'This means supporting the new UN Representative and the political process.

'But it also means practical efforts too – including the new kit we are providing to make Sirte safer for Libyans and the work we are doing to ensure that the Libyan coastguard can secure their own borders, reducing the number of illegal migrants heading for Europe.'

The money includes £3 million to remove improvised explosive devices from Sirte, following the success in pushing ISIS out of the city earlier this year.

Another £1million will fund demining training across Libya, including in Sirte and Benghazi.

While £1million to help rebuild critical infrastructure and restore basic public services and £2.75 million to support women’s participation in peacemaking and rebuilding Libya. Another £1.29 million of new UK aid funding over the next two years to provide people with desperately needed food and medicine.  

The package of aid announced by Mr Johnson following talks with the Libyan Prime Minister.

The pair talked about what more the UK could do to support Mr Al-Serraj's Government of National Accord and the UN-led peace and stabilisation process.

Ahead of Mr Johnson's visit, Mr Al-Serraj warned that would-be terrorists could be entering Europe among the tens of thousands of migrants making the perilous Mediterranean crossing, 

He told : 'When migrants reach Europe, they will move freely. 

'If, God forbid, there are terrorist elements among the migrants, a result of any incident will affect all of the EU.'  

He added: 'The EU must do more to us help face smuggling. We can't put the burden on Libya and Italy alone as it is important for all of Europe.'

Mr Johnson also met members of the Libyan Naval Coastguard to hear about their UK training in search and rescue, boarding and inspecting vessels, human rights and the treatment of migrants.
