London, July 28 (IANS) The cost of British military operations in Afghanistan was Thursday officially estimated at over 18 billion pounds (around $29 billion), The Guardian reported.

The figures released by the House of Commons defence committee also show the cost of imposing a UN-backed no-fly zone in Libya as well as the cost of bombing targets at 260 million pounds (around $424 million).

The report, however, stated that these were just estimates.

‘The total cost of operations in Afghanistan is not known,’ and that it was ‘too early to forecast the cost of British operations in Libya’.

The committee said that this year itself military operations in Afghanistan will cost more than four billion pounds.
