Secretary of State Hillary Clinton in a speech on Monday after the U.S. announced it had killed Osama bin Laden, said the U.S. and allies would continue to take the fight to al-Qaida and the Taliban, saying you cannot defeat us.

Clinton was speaking just hours after President Barack Obama announced a small team of U.S. special forces arriving by helicopter at Bin Laden's compound 35 miles from Islamabad, Pakistan killed the leader in a firefight.

In Afghanistan we will continue taking the fight to al-Qaida and their Taliban allies while working to support the Afghan people as they build a stronger government and begin to take responsibility for their own security, Clinton said.

Our message to the Taliban remains the same, but today it may have greater resonance: you cannot wait us out, you cannot defeat us, but you can abandon al-Qaida and participate in a peaceful political process, Clinton said.

Clinton began her speech by recalling the victims of the September 11, 2001 attacks.

I want to offer my thoughts and prayers to thousands of families of those killed in terrorist attacks, she said.

I know that nothing can make up for the loss of the victims or fill the void they left. But I hope they can find some comfort in the fact that justice has been done, she said.
