2012 London Olympics organizers will spend 31.4 million U.S. dollars of reserve funds to modify Olympic facilities under security concerns, the British government said on Monday.

The government said in its latest quarterly report that the extra security spending would not affect the anticipated final cost of the Olympics thanks to other savings.

It said the Olympic Park facilities needed to be modified in order "to make them more secure and resilient to attacks".

A total of 2.09 billion dollars contingency remains unallocated, even after more than 1.15 billion dollars of the fund has been spent in offsetting the effects of the global financial crisis.

The anticipated cost of the Olympics is at 11.9 billion dollars.
