A remembrance service was being held at St Aloysius Church in Euston when shots were reportedly fired from a moving vehicle on Saturday afternoon.The seven-year-old, who was taken to a central London hospital at about 14:05 GMT, "remains in hospital in a life-threatening condition"."I can assure the communities of Camden and beyond that we will do everything we possibly can to identify and bring to justice those who were responsible.""They were very scared, people sheltered in the church until the police said they can leave but some of them were so scared they had to wait a while to get their confidence back up to go outside."Photographer Simon Lamrock said when he first arrived at the church, people had been evacuated through a side entrance."
