Speaking on Saturday afternoon, Mr Leterme told journalists that "there is a unanimous will on the part of the countries participating to ensure that UN resolution 1973 is upheld, if necessary by the use of military force.”
Mr Leterme concluded by saying that all criteria for Belgium to contribute to an international operation had been fulfilled.
In the meantime British, American and French planes have carried out operations. French planes bombed positions just outside Benghazi. British planes have also carried out air raids on Libyan Government positions. Elsewhere British and US Navy ships attacked Libyan air defences from the sea.
