LONDON (AP) – The head of the SITE intelligence group says the Islamic State group has claimed responsibility for the London attacks.

The SITE Intelligence Group says Islamic State’s news agency is claiming fighters for the extremist group carried out the van and knife attack in London that left seven people dead.

SITE said in a statement Sunday that the Islamic State’s Aamaq news service cited “a security source” in the Arabic-language posting claiming the attack.

Islamic State has often made such claims not just when it has sent attackers, but when extremists carrying out deadly plots were inspired by the group’s ideology.

It’s the third attack this year that Islamic State has claimed in Britain, after the bombing in Manchester and a similar attack in the heart of London in March.

The three attackers in Saturday’s attack have not been identified.
