[Ed. – ISIS has already claimed responsibility for the attack. We may never know the motive, of course.]
An “improvised explosive device” was detonated on a Tube train in south-west London during Friday’s morning rush hour, injuring 29 people.
The blast, at Parsons Green station on a District Line train from Wimbledon, is being treated as terrorism.
So-called Islamic State says it carried out the attack, which Prime Minister Theresa May condemned as “cowardly”.
A hunt is under way for the person who placed the device and the area around the station has been evacuated.
Specialist officers there securing the remains of the improvised device and ensuring it is stable.
