LONDON (Reuters) - British police believe an attack in London that left four people dead and injured around 40 was linked to Islamic terrorism and are checking whether the lone attacker was supported by anyone else, the defence minister said on Thursday.

“The police are investigating this man, his associates, where he came from,” Michael Fallon told BBC Radio. “(They are) checking urgently whether other people were involved in this. Their working assumption is that this is linked to Islamic terrorism.”
