LONDON - The British government has put extra soldiers on standby to provide security for the London Olympics following concerns the private contractor G4S would not train enough guards in time for this month's Games.

Some 23,700 security guards will protect the Olympic venues as part of Britain's biggest peacetime security operation, and 13,500 military personnel have already been earmarked to contribute to this.

However, fears over whether G4S would recruit enough guards in time has prompted the government to take action with the Olympics due to start on July 27.

"We have agreed to offer help to G4S by revising the level of military support," a spokeswoman for the Home Office said.
