NATO admits they shot down a Libyan rebel MiG 23.  This is causing more problems between rebels and NATO.  NATO has bombed rebel ground troops several times now.

NATO says the downing of the rebel aircraft shows that they are enforcing the UN “no-fly zone”.  NATO says the no-fly zone applies to any Libyan aircraft.

The reason for NATO suddenly attacking a rebel aircraft, could be that the Libyan government has complained that rebel helicopters are being allowed to fly, despite the UN resolution stating that ALL military aircraft would be shot down by the coalition.
