Police in London have now given a likely final death toll of around 49 for Thursday's terror attacks.
All visible bodies have been removed from the four blast sites.
However, British Transport Police Deputy Chief Constable Andy Trotter said rescue workers are continuing to search beneath an underground train between King's Cross and Russell Square to see if any had been missed.
It had been feared the number of victims might eventually exceed 70 but detectives say that is highly unlikely.
The bodies are being taken to a temporary mortuary at an undisclosed military site but none has yet been formally identified.
A total of 59 family liaison officers have so far been deployed to families whose loved ones are missing.
Between 20 and 40 people are currently regarded as 'missing'. More than 60 people are still in various London hospitals, 15 of whom are said to be serious or critical.
Police have said it could be weeks before some families find out if their relatives are among the dead.
Earlier today, it emerged that three men have been arrested at Heathrow Airport under Britain's terrorism legislation, though police say there is no established link with Thursday's bombing.
Deputy Assistant Commissioner Brian Paddick told a news conference this afternoon that it would be inappropriate and speculative to draw any links with the attacks in London.
