The police always call it that first, they did with the London bridge attack also. It was only later that they called it terrorist. I think you are seeing more into that than you should.
Anyway, here is an update:
TWO people are feared dead and several injured after a van reportedly rammed into pedestrians in a “terrorist attack” outside a mosque in north London.
One man was arrested after witnesses said the van deliberately accelerated into a crowd of Muslim worshippers on Seven Sisters Road in Finsbury Park.
London’s Evening Standard reports the van driver was armed with a knife and jumped out of the vehicle and stabbed one person. Others said there were three white men in the van and two escaped.
