Boat passengers jump in River Thames as flames rip through London Duck Tours vessel
Some 30 people have been rescued after a blaze tore through an amphibious tourist boat opposite the Houses of Parliament.
Flames ripped through the London Duck Tours vessel on a stretch of the River Thames close to Lambeth Bridge.
Many of those on board leapt into the water as flames took hold and thick black smoke billowed from the burning boat.
Passengers were later hauled to safety by rescue workers and crews on passing tour barges.
A woman and a child were taken to hospital with suspected smoke inhalation while further tourists were treated at the riverside.
A police source said the nature of the injuries "could have been a lot worse".
Some 28 tourists and two members of crew were on Sunday's stricken tour.
London Fire Brigade said the beleaguered craft was 33% damaged by the fire, which broke out shortly before midday.
A Scotland Yard spokesman said: "Police were called at approximately 11.55am to reports of a fire on a Duck Tours boat on the River Thames."
The LFB has launched an investigation into how the fire started.
The Port of London Authority is also expected to investigate the blaze.
