World leaders react to the Nobel Peace Prize announcement
US President Barack Obama has won the 2009 Nobel Peace Prize for his "extraordinary efforts" to build diplomacy and promote nuclear disarmament.
Since coming to office in January, President Obama has pursued an international agenda that includes a push to restart peace talks in the Middle East and negotiations over Iran's controversial nuclear programme.
Here is a round-up of world reaction to the award as reported by news agencies.
UN SECRETARY-GENERAL BAN KI-MOON
We are entering an era of renewed multilateralism, a new era where the challenges facing humankind demand global common cause and uncommon global effort. President Obama embodies the new spirit of dialogue and engagement on the world's biggest problems: climate change, nuclear disarmament and a wide range of peace and security challenges.
FRENCH PRESIDENT NICOLAS SARKOZY
It confirms, finally, America's return to the hearts of the people of the world... you can count on my resolute support and that of France.
ANGELA MERKEL, GERMAN CHANCELLOR
In a short time he has established a new tone, creating a willingness for dialogue and I think we all should support him to make peace in this world possible. There is a lot do but a window of opportunity has been opened. His advocacy of a world free of nuclear arms is an aim we all need to make real in the next few years.
YUKIO HATOYAMA, JAPANESE PRIME MINISTER
I am really pleased. I want to congratulate him from my heart. I've seen the world changing since President Obama took office. It was outstanding when he made the speech in Prague calling for a nuclear-free world.
NATO SECRETARY GENERAL ANDERS FOGH RASMUSSEN
President Obama has made extraordinary efforts to strengthen international diplomacy and co-operation between peoples.
He has also demonstrated his strong commitment to help build peace and defend fundamental human rights, including through the atlantic alliance. This honour is well deserved.
MOHAMED ELBARADEI, HEAD OF THE INTERNATIONAL ATOMIC ENERGY AGENCY AND NOBEL PEACE PRIZE WINNER
There is nobody today in my view who is more deserving of that peace prize than Barack Obama. In less than a year he brought a radical change in the way we look at ourselves, in the way we look at our world. He is restoring the basic core values that every one of us should live by - dialogue, respect, democracy, due process, human rights, a security system that does not depend on nuclear weapons. His dedication to these values rekindles hope that, finally, we could have a world at peace with itself.
IRANIAN FOREIGN MINISTER MANOUCHEHR MOTTAKI
We have no objection if this prize is an incentive to reverse the warmongering and unilateral policies of the previous US administration and if this encourages a policy based on just peace.
The appropriate time for awarding such a prize is when foreign military forces leave Iraq and Afghanistan and when one stands by the rights of the oppressed Palestinian people.
SIAMAK HIRAI, SPOKESMAN FOR AFGHAN PRESIDENT HAMID KARZAI
We congratulate Obama for winning the Nobel. His hard work and his new vision on global relations, his will and efforts for creating friendly and good relations at global level and global peace make him the appropriate recipient of the Nobel Peace Prize.
TALIBAN SPOKESMAN ZABIHULLAH MUJAHID
We have seen no change in his strategy for peace. He has done nothing for peace in Afghanistan. He has not taken a single step for peace in Afghanistan or to make this country stable.
We condemn the award of the Nobel Peace Prize for Obama. We condemn the institute's awarding him the peace prize. We condemn this year's peace prize as unjust.
BENJAMIN NETANYAHU, ISRAELI PRIME MINISTER
You have already inspired so many people around the world, and I know that this award also expresses the hope that your presidency will usher in a new era of peace and reconciliation. Nowhere is such a peace needed more than in the Middle East, a region that has been long marked by terror and bloodshed.
I look forward to working closely with you in the years ahead to advance peace and to give hope to the peoples of our region who deserve to live in peace, security and dignity.
We hope that he will be able to achieve peace in the Middle East and achieve Israeli withdrawal to 1967 borders and establish an independent Palestinian state on 1967 borders, with Jerusalem as its capital.
HAMAS LEADER ISMAIL HANIYEH
We are in need of actions, not sayings. If there is no fundamental and true change in American policies toward the acknowledgment of the rights of the Palestinian people, I think this prize won't move us forward or backward.
MIKHAIL GORBACHEV, FORMER SOVIET LEADER AND NOBEL PRIZE WINNER
I am happy. What Obama did during his presidency is a big signal, he gave hope. In these hard times, people who are capable of taking responsibility, who have a vision, commitment and political will should be supported.
SOUTH AFRICAN ARCHBISHOP AND NOBEL PEACE PRIZE WINNER DESMOND TUTU
He's not even finished a year in his first term of office of a relatively young president. It's an award that anticipates an even greater contribution towards making our world a safer place for all.
FORMER POLISH PRESIDENT AND NOBEL PRIZE WINNER LECH WALESA
So soon? This is too soon. He has not yet made a real input. He is still at an early stage. He is only beginning to act.
This is probably an encouragement for him to act. Let's see if he perseveres.
FORMER US PRESIDENT AND NOBEL PEACE PRIZE WINNER JIMMY CARTER
It is a bold statement of international support for his vision and commitment to peace and harmony in international relations. It shows the hope his administration represents not only to our nation but to people around the world.
FORMER US VICE-PRESIDENT AND NOBEL PEACE PRIZE WINNER AL GORE
I think it's extremely well deserved. I think it will take some time before people put together all the different moves that linked his speech at the UN on the abolishing of nuclear weapons, his shift on the missile defence programme in Eastern Europe and the movement of Russia to joining the international consensus that confronted Iran to abide by the non-proliferation treaty.
JODY WILLIAMS, FORMER NOBEL PEACE PRIZE WINNER FOR CAMPAIGN TO BAN LANDMINES
I think that it is kind of foolish to think that the Nobel Prize isn't politicised - it's not a humanitarian prize, it's a prize in recognition of change in the world to contribute to peace, sometimes its a recognitions of visions for peace. He is facing huge contradictions as well - he is going to be sending 40,000 new American troops into Afghanistan just as he receives the Nobel Peace Prize? I think that is a contradiction that needs to be seriously looked at.
SOUHAYR BELHASSEN, PRESIDENT OF INTERNATIONAL FEDERATION OF HUMAN RIGHTS
Awarding the Nobel Peace Prize to Obama is a way of encouraging him to not renege on the universal principles that he has championed.
We would have preferred a human rights defender like Oleg Orlov from Memorial in Russia or Natalia Estemirova [human rights activist murdered in Chechnya].
