As police confirm the Parsons Green explosion as a terror-related incident, experts have judged the Underground bomb a crude failure.
An unknown number of civilians, including children, have been left injured after a ‘fireball’ ripped through a tube train carriage at Parsons Green station this morning just before 8:20am.
The device in question was made from fairy lights, a builder’s bucket, an ALDI cooler bag and a black cloth; with one witness, Sylvain Pennec adding, ‘It looked like a bucket of mayonnaise.’
Pennec continued: ‘I’m not sure if it was a chemical reaction or something else, but it looked home made. I’m not an expert though.’
Meanwhile, the Met’s Counter Terrorism Command are investigating after the explosion was declared a terrorist incident just after 10am this morning.
Major General Chip Chapman told Sky News:
This doesn’t look like a high-end [device] from ISIS such as TATP or if it was, it failed significantly or the booster or detonator, so at the moment you have to keep an open mind.
That said of course, the most devastating land-based terror attack in Europe, in Madrid, had a similar modus operandi, so the MO could suggest something.
But it could just be something as benign as chemicals, or someone going to work with some Flash, but we can say that at the moment it’s not a high-explosive that functioned because the blast and shockwave would have killed multiple people.

Emergency services, including the ambulance service, the London Fire Brigade and British Transport Police were called to the West London station at around 8:20am.
Passengers on the train have reportedly suffered ‘facial burns‘ during their Friday morning commute, with eyewitnesses describing a ‘fireball’ and people ‘covered in blood’.
Another eye-witness report described a panicked scene resulting in a ‘stampede’ to safety on Twitter.
There have been further warnings issued after a suspect armed with a knife is said to be on the run in London following the Parsons Green explosion.
British Transport Police have asked everyone to remain vigilant and to report any suspicious behaviour by texting 61016 or calling 0800 405040.
