US President Barack Obama pledged on Tuesday that the United States will continue its previous efforts to fight against terrorism.

"We will forge a new and comprehensive strategy for Afghanistan and Pakistan to defeat al Qaeda and combat extremism," said Obama in his first address to a joint session of the Congress.

"I will not allow terrorists to plot against the American people from safe havens half a world away," he said.

On the US foreign policy, Obama reiterated his commitment to broaden American exchanges with the world, saying: "In words and deeds, we are showing the world that a new era of engagement has begun."

"We cannot shun the negotiating table, nor ignore the foes or forces that could do us harm. We are instead called to move forward with the sense of confidence and candor that serious times demand."

On the Middle East peace process, Obama said the United States is seeking progress toward a secure and lasting peace between Israel and her neighbors. "We have appointed an envoy to sustain our effort" in the Mideast peace process, he said.

"To meet the challenges of the 21st century from terrorism to nuclear proliferation; from pandemic disease to cyber threats to crushing poverty we will strengthen old alliances, forge new ones, and use all elements of our national power," the president added.
