NATO says it has disabled three Libyan state TV satellite transmission dishes in the capital Tripoli, through a precision air strike. It said the operation was intended to stop inflammatory broadcasts by Col Muammar Gaddafi's regime. NATO said it was in the process of assessing the effect of the strike. A NATO statement said the strike was performed by its fighter aircraft using state-of-the-art precision guided munitions, and that there has been due consideration and careful planning to minimise the risks of casualties. Libyan state TV was still on air following the NATO statement. Coalition forces began operations in Libya in March, under a UN mandate authorising military action for the protection of civilians. Libyan rebels began an uprising against Col Gaddafi in February. Despite NATO's intervention, they have struggled to break a military deadlock.
