London CNN  — 

Nearly two weeks on from the suicide bombing at the Manchester Arena, there was a sense in Britain that – at least for those not directly affected by that attack – life was slowly returning to normal.

Landmarks in London and across the UK had been on a heightened state of alert, as the country’s terror threat level was raised to critical in the aftermath of the bombing.

But as of last weekend, that threat had been reduced one level down to severe, and attention was shifting back to everyday life.

On a beautiful sunny Saturday at the end of a mid-semester school holiday, London had been as busy and thriving as it always is.

Forensic officers work at the scene of a terror attack at London Bridge in London on Sunday, June 4. At least seven people were killed in attacks late Saturday as a van mowed down pedestrians on London Bridge before attackers then stabbed victims at nearby Borough Market.
