From the BBC:
President Barack Obama of the US, Prime Minister David Cameron of the UK and President Nicolas Sarkozy of France have written a joint letter to The Times of London, the International Herald Tribune and Le Figaro, vowing to keep up the pressure on Libyan leader Muammar Gaddafi and pledging to maintain Nato military pressure on his forces.
The full text of the letter is below.
Together with our Nato allies and coalition partners, the United States, France and Britain have been united at the UN Security Council, as well as the following Paris Conference, in building a broad-based coalition to respond to the crisis in Libya. We are equally united on what needs to happen to end it.
Even as we continue military operations today to protect civilians in Libya, we are determined to look to the future. We are convinced that better times lie ahead for the people of Libya, and a pathway can be forged to achieve just that.
We must never forget the reasons why the international community was obliged to act in the first place. As Libya descended into chaos with Colonel Gaddafi attacking his own people, the Arab League called for action. The Libyan opposition called for help. And the people of Libya looked to the world in their hour of need.
In an historic resolution, the United Nations Security Council authorised all necessary measures to protect the people of Libya from the attacks upon them. By responding immediately, our countries halted the advance of Gaddafi's forces. The bloodbath that he had promised to inflict on the citizens of the besieged city of Benghazi has been prevented.
Tens of thousands of lives have been protected. But the people of Libya are suffering terrible horrors at Gaddafi's hands each and every day. His rockets and his shells rained down on defenceless civilians in Ajdabiya. The city of Misrata is enduring a medieval siege as Gaddafi tries to strangle its population into submission. The evidence of disappearances and abuses grows daily.
Our duty and our mandate under UN Security Council Resolution 1973 is to protect civilians, and we are doing that. It is not to remove Gaddafi by force. But it is impossible to imagine a future for Libya with Gaddafi in power. The International Criminal Court is rightly investigating the crimes committed against civilians and the grievous violations of international law. It is unthinkable that someone who has tried to massacre his own people can play a part in their future government. The brave citizens of those towns that have held out against forces that have been mercilessly targeting them would face a fearful vengeance if the world accepted such an arrangement. It would be an unconscionable betrayal.
Furthermore, it would condemn Libya to being not only a pariah state, but a failed state too. Gaddafi has promised to carry out terrorist attacks against civilian ships and airliners. And because he has lost the consent of his people any deal that leaves him in power would lead to further chaos and lawlessness. We know from bitter experience what that would mean. Neither Europe, the region nor the world can afford a new safe haven for extremists.
There is a pathway to peace that promises new hope for the people of Libya: a future without Gaddafi that preserves Libya's integrity and sovereignty and restores her economy and the prosperity and security of her people. This needs to begin with a genuine end to violence, marked by deeds, not words. The regime has to pull back from the cities it is besieging, including Ajdabiya, Misrata and Zintan, and its forces return to their barracks.
However, so long as Gaddafi is in power, Nato and its coalition partners must maintain their operations so that civilians remain protected and the pressure on the regime builds. Then a genuine transition from dictatorship to an inclusive constitutional process can really begin, led by a new generation of leaders. For that transition to succeed, Colonel Gaddafi must go, and go for good. At that point, the United Nations and its members should help the Libyan people as they rebuild where Gaddafi has destroyed - to repair homes and hospitals, to restore basic utilities, and to assist Libyans as they develop the institutions to underpin a prosperous and open society.
This vision for the future of Libya has the support of a broad coalition of countries, including many from the Arab world. These countries came together in London on March 29 and founded a contact group that met this week in Doha to support a solution to the crisis that respects the will of the Libyan people.
Today Nato and its coalition partners are acting in the name of the United Nations with an unprecedented international legal mandate. But it will be the people of Libya, not the UN, who choose their new constitution, elect their new leaders and write the next chapter in their history.
Britain, France and the United States will not rest until the United Nations Security Council resolutions have been implemented and the Libyan people can choose their own future.
