'IS uses companies in Wales to finance terrorist attacks against the West'

The surveillance technology dispatched to Spain — where 14 people were killed last week in the latest Isis-inspired atrocities — is understood to be linked to the development by the terrorist group of weaponised drones. The FBI says it was capable of identifying "target locations".

An affiliated firm was used to transfer thousands of pounds in cash to an American extremist in Maryland who later told how he dreamt of carrying out a gun massacre in a church. Other purchases said to be routed through Cardiff in Wales include orders for "bug sweep units" and software to help launch rockets.

US court documents seen by the newspaper show the lengths to which individuals involved with the Wales companies went to mask their alleged activities.

One of the firms which shipped surveillance equipment to Madrid, Spain appears to have been set up using the identity of a bogus director and shareholder called "Peter Soren". The name is believed to be an alias for Siful Sujan, a Bangladesh-origin IT expert and businessman behind the companies who left south Wales three years ago with his family to join the ISIS in Syria.

He was later killed by a US drone strike in Raqqa, the terror group's de facto capital.

Sujan and his associates originally set up the Ibacs network of companies to offer website and printing services to restaurants and takeaways.

They operated out of an office on Alexandra Gate business park at Tremorfa in Cardiff. But a probe involving the FBI in the US and British anti-terrorist police discovered that some of the companies became involved in more sinister activities after Sujan headed to Syria, where he was a senior figure in ISIS hacking operations and weapons development.

One of the Cardiff-based firms, Ibacstel Electronics, was used to send a total of USD 7,700 in 2015 to an ISIS supporter in Maryland, US, called Mohamed Elshinaway, 32, who pleaded guilty to terrorism charges last week.

In July 2015 a company called Advance Technology Global (ATG) was created and registered at the Alexandra Gate business address, the FBI claims.

Transcripts of a Skype conversation between Sujan and another Ibacs director in Cardiff obtained by the FBI reveal that Sujan was the real brains behind ATG. Sujan came to the UK to study in 2003 and was followed by his wife, Akter, two years later. They had a son, Amanul, in 2011 and lived in Pontypridd, but later moved to a rented townhouse in Cardiff, close to the Alexandra Gate business park.

The couple briefly moved back to Bangladesh before travelling to Turkey with their son.

Ibacstel Electronics was dissolved in March 2016 and ATG was wound up eight months ago. The FBI disclosures will raise fears about the likelihood of further attacks in Europe.
