Washington: US Secretary of State Hillary Clinton has met her British counterpart William Hague here to discuss a wide range of issues ranging from the current situation in Afghanistan, Pakistan, Middle East and the European debt crisis.

"Our meeting today reflected a wide array of shared concerns and challenges, including the economic crisis in Europe, the attack on the UK embassy in Iran, the transition in Afghanistan, the situation in Pakistan, the evolving situations in Burma, North Africa, the Middle East, the Balkans and so much more. We lost track of all of the matters which we went over today," Clinton told reporters.

Besides discussing the Europe's debt crisis, the two leaders discussed the ongoing efforts to press the Iranian government to meet all of its international obligations, she said.

"The attack on the British embassy was an affront not only to the British people, but to the international community. Governments owe a duty to protect diplomatic lives and property, and we expect the government of Iran to do just that, both inside and outside of Iran," Clinton said.

"That is why we strongly supported the UN General Assembly's resolution deploring the plot to assassinate the Saudi ambassador here in Washington, and we're working together on additional sanctions and the great work that the foreign minister and the government of UK has done with us at the IAEA to express nearly unanimous concern about Iran's nuclear programme," she said.

However, a big part of the discussion was focused on Afghanistan following up on our meetings in Bonn and the ISAF meeting in Brussels at NATO, Clinton said.

"The British and American men and women of our armed forces have literally stood and fought side by side and have reversed the Taliban momentum on the battlefields," the US leader said.

"And our diplomats and development experts have likewise stood shoulder to shoulder to try to help the people of Afghanistan realise a better future. As we talk about transitioning security, we look very clearly at the goal that was set at the Lisbon summit. This transition is a new phase of support for Afghanistan, not the end of our commitment. We will stay very closely connected as we move through this period as well," Clinton said.

Reiterating that the United States is Britain's closest and indispensable ally in foreign policy, British Foreign Secretary William Hague said they have discussed a very broad range of challenges that the two countries are facing.

"As everyone knows, we've had in 2011 a momentous year in world affairs, and I think we've risen to these challenges with confidence. Our joint efforts in Libya, for instance, to save lives, benefited from the seamless cooperation in diplomacy and in defence which is one of the distinctive hallmarks of the relationship between the UK and the US," he said.

Hague said that Britain will continue to work in war-torn Afghanistan with its other allies, as the issue will be one of the major focus in the Chicago summit to be held in May next year.
