Low-level combat exercises will continue in the skies over Norfolk until the middle of next week.

An infantry brigade about to be deployed in Afghanistan is being trained in how to call in air strikes on Taleban positions.

Aircraft attacking enemy troops come in fast and low to engage them and attacks could take place both day and night.

RAF aircraft including Tornado GR4s from Marham will be participating in the exercise, and there will be

an increase in flying until midnight on Monday, Tuesday and Wednesday of next week.

Defence sources said in the field the role of the forward air controller on the ground was crucial. If the wrong co-ordinates were given, British fatalities could result.
