ISIS claims responsibility for London stabbing; judgement on Pak-origin attacker had spoken of his madrassa radicalisation

Director of SITE Intelligence Group Rita Katz tweeted: "BREAKING:#ISIS claims #LondonBridgeAttack via #Amaq- calling perp an "Islamic State fighter," despite comm. setbacks. The claim itself is not surprising, as the attack bore IS-inspired hallmarks-though coming only 1 day after shows cont'd media capability."

The man, who carried out the stabbing incident in London on Friday killing two people, was of Pakistan origin and once wanted to establish Sharia Law. He even had planned to build a terror training camp in Kashmir.

Sharia law is a religious law forming part of the Islamic tradition. It is derived from the religious precepts of Islam, particularly the Quran and the hadith.

According to sources, 28-year-old Usman Khan lived in Pakistan for one term before turning into a terrorist for the first time.

Khan, who was shot dead by security forces during Friday's attack, pleaded guilty in 2012 for preparing acts of terrorism as a member of an al-Qaeda-inspired terrorist cell that had planned to attack the London Stock Exchange, sources said.

"He originally received an indeterminate sentence for public protection but this was quashed at the Court of Appeal in April 2013 and he was given a 16-year jail term," a source said. 

The judgment against Usman said: "It is clear to me that Usman Khan and Nazan Hussain were to attend the madrassa and were themselves keen to perform acts of terrorism in Kashmir and that it was envisaged that when they and others, who had been recruited, had also trained in the Madrassa and had experience in Kashmir, they may return to UK and perform acts of violent terrorism here."

"The long, monitored, discussions of Usman Khan about the madrassa and his attitude towards it and terrorism are highly eloquent of the seriousness of their purpose," it said.

"It is clear that it was a serious, long term, venture in terrorism the purpose of which was to establish and manage a terrorist training facility at the Madrassa, to fundraise for its construction and operation by the use of various means, including fraud, and to recruit young British Muslims to go there and train, thereafter being able to commit terrorism abroad and at home.Added to this is the dimension of all of this being the subject of discussion at, and their participation in the larger group in which they were pre-eminent and of which Shahjahan was regarded as the ameer," said the judgment.

Met Police Assistant Commissioner Neil Basu said Khan was known to the authorities and had been convicted for terrorism offenses in 2012.

Basu said, "We are now in a position to confirm the identity of the suspect as 28-year-old Usman Khan, who had been residing in the Staffordshire area. As a result, officers are, tonight, carrying out searches at an address in Staffordshire."

"This individual was known to authorities, having been convicted in 2012 for terrorism offences. He was released from prison in December 2018 on licence and clearly, a key line of enquiry now is to establish how he came to carry out this attack," he said.

Pakistan origin:

Khan left school with no qualifications after spending part of his late teens in Pakistan, where he lived with his mother when she became ill.

On his return to the UK, he started preaching radical Islam on the internet and attracted a significant following, said sources.

Kashmir connection:

Khan had planned to use land owned by his family in Kashmir to build a terror training camp next to an existing mosque, in the hope of establishing Sharia law in the region, sources said.
