Three people died and more than 60 were injured - at least 13 seriously - when a nail bomb ripped through a pub frequented by gays in the heart of central London last weekend.
No warning was given before the explosion at the Admiral Duncan in Old Compton Street, in Soho - the third nail bomb in London in less than two weeks.
The blast sent shards of glass flying into the street, hitting passers-by and damaging numerous restaurants and bars. Half a dozen of the injured could lose their limbs, said a consultant at St Thomas's hospital in London. Many patients would require plastic surgery.
A man was remanded in custody on Monday in connection with the three bombings.
David Copeland, aged 22, an engineer from Cove, near Farnborough, Hampshire, was charged with three counts of murder and three of causing an explosion to endanger life.
Police sources said they were not looking for anyone else in connection with the nail bombings.
The three who died were among a group of five having a drink in the pub before going to the theatre to see a musical.
Andrea Dykes, aged 27, from Colchester, Essex, was four months pregnant. John Light, aged 32, also from Colchester, had been her husband's best man at their wedding, and Nicholas Moore, aged 31, who lived in London, had been friendly with the Dykes for several years.
Mrs Dykes's husband, Julian, aged 25, was fighting for his life in hospital unaware of her death. The fifth person in the group, Gary Partridge, was in a critical condition.
Nineteen people remained in hospital with burns and limb injuries. Four men were critically injured, three of whom had had legs amputated.
Three people remain in hospital after the Brixton blast on April 17, which injured 39 people. A week later another nail bomb in Brick Lane, east London, injured seven.
After the Brixton bomb police received at least four phone calls from neo-Nazi organisations, including Combat 18, claiming responsibility for the attack.
The Soho bomb showed a chilling determination to cause maximum harm. Police said the bomb had been in a bag placed beside the bar. By planting the device in a crowded bar at one of the busiest times of the day, the bomber knew people would be killed.
The pub was full when the bomb went off and the street alive with hundreds of people leaving work to enjoy the early evening sun at the start of the May Day weekend.
Twenty-one ambulances were sent to the scene, including two air ambulances, which ferried casualties to hospital. A field hospital was set up in Soho Square to deal with some of the injured. Thousands of people were evacuated from the area, including theatre-goers, clubbers and diners.
After the black community in Brixton, and the Bangladeshis in Brick Lane were targeted, there were fears that another minority group would be the third victim - Old Compton Street is the heart of the capital's gay community.
At a vigil in Soho last Sunday, attended by more than 2,000 people, there were cheers and claps as Metropolitan police chief superintendent Jo Kaye announced that a man had been charged.
In a speech to Sikh leaders in Birmingham last weekend, the Prime Minister said: "The true outcasts today, the true minorities, those truly excluded are not the different races and religions of Britain but the racists, the bombers, the violent criminals who hate that vision of Britain and try to destroy it."
