Security sources have warned that six terror suspects have entered the UK using small boats to cross the English Channel.
It is believed that they have travelled from Syria and are “planning to attack government” buildings across various sites in the United Kingdom.
MI6 operatives stationed near to Syria’s capital, Damascus uncovered details of a plot being supported by Iranian paymasters who have direct links to Islamist groups.
MI6 knew of the terrorist plot before the Iranian back militant group Hamas carried out their deadly attack in southern Israel on 7 October.
The Express reported that an intelligence source said, “The information indicates that these people are terrorists planning to attack government buildings in England, Scotland and Wales.
“Although they arrived without identification, we believe all are now in possession of false documents.
“They plan to commit an act which embarrasses the Government.
“This could mean damaging a building or even a close-proximity cyber attack, though we do not anticipate this is a mass-casualty event.”
The Islamist terror group entered the UK illegally weeks ago from northern France after travelling from Syria.
Security sources are monitoring the movements of three suspects and the others are using fake IDs and they do not know where they are.
So far this year it is believed that around 25 terror suspects have crossed the English Channel and are now freely moving around the UK.
Former counter-terror police chief Chris Phillips said, “The Rwanda scheme will not fix this by itself but, by deterring migrants, it will allow the authorities more scope to keep an eye on who is landing.”
Former local government minister Lia Nici said, “While we allow illegal migrants to walk freely around the UK with no true knowledge of who they really are or the real reasons for them coming here, we are opening ourselves up to risks.
“While we allow non-democratic courts to overrule democratically made laws, we will never be able to secure our borders. Increasing numbers of European countries are realising what this means for security. It is time the Home Office did too.”
Alan Mendoza, of the Henry Jackson Society think-tank, said: “We have known for some time how difficult it has proved to monitor the identities of illegal migrants.
“And the more migrants who make that journey, the more the threat grows. The only solution is for the Government to act urgently, whether it is through the Rwanda route or another measure.”
Former cabinet minister Simon Clarke said, “As this news shows, this isn’t a matter just of immigration enforcement but of national security.
“For as long as we don’t know who is coming to the UK there is a threat which it is a fundamental responsibility of the Government to address.”
