British Prime Minister Theresa May has joined survivors, victims' families and emergency workers at a memorial service to mark a year since a deadly vehicle-and-knife attack brought terror to London Bridge on a warm Saturday night.
Eight people were killed and almost 50 injured when three Islamic State group-inspired extremists ran down pedestrians on the bridge, then stabbed people at packed bars and restaurants in nearby Borough Market, one of London's main foodie hubs.
Among the dead were Australian women Sara Zelenak, 21, and Kirsty Boden, 28. The three attackers were shot dead by police within minutes.
The rampage came two weeks after a bombing at an Ariana Grande concert in Manchester Arena that killed 22 people.
More than 700 people gathered on Sunday inside the centuries-old Southwark Cathedral, nestled between the bridge and the market on the lively south bank side of the River Thames.
Dean of Southwark Andrew Nunn said he hoped the service of remembrance "helps our healing".
"Love is stronger than hate. Light is stronger than darkness. Life is stronger than death," he said. "It was true a year ago. It is as true today."
After the service, families of the dead planned to plant an olive tree on the cathedral grounds before a national minute's silence at 4.30pm The words (hash)LondonUnited were due to be projected on to the bridge late on Sunday.
In a statement, the prime minister paid tribute to the bravery of first responders and others, including Ignacio Echeverria, a Spanish man who tackled the attackers with his skateboard and was killed.
May said the fact that seven of the eight victims came from outside Britain - from Australia, France, Spain and Canada - was "a reflection of our great cosmopolitan capital, whose energy and values brings together people from across the world, and a tragic reminder that the threat from terrorism transcends borders and impacts us all.
"Our resolve to stand firm and overcome this threat together has never been stronger," she said.
