Britain is deploying another 1,200 soldiers in a last-minute effort to bolster Olympic security.
According to Sky News, the government announced that soldiers, who were put on standby last week, are now being called up as a precaution.
The decision was taken by ministers at a Cabinet Committee for the Olympics, which was chaired by Prime Minister David Cameron.
The latest deployment takes the total number of troops involved to guard the games to around 18,000.
Culture Secretary Jeremy Hunt said that the number of guards being provided by struggling security firm G4S is rising, but ministers would 'leave nothing to chance'.
"Security staffing levels at venues have been kept under constant review. G4S numbers continue to rise significantly and we have every expectation that will continue to be the case," he said.
"However, ministers decided that we should deploy the additional 1,200 troops that were put on standby last week," he added.
LOCOG Chief Executive Paul Deighton said: "The reason that this decision has been taken is just to absolutely de-risk any aspect of the operation. With three days to go, we just want to make sure this works without any worries at all."
Metropolitan Police Assistant Commissioner Chris Allison said it was "without doubt the biggest peace time policing operation we have had to do."
He said they were well prepared for the areas of threat, including terrorism, organized crime, protests and natural hazards. (ANI)
