Terrorists around the world should not forget that the United States will hunt them down, the chairman of the Senate Foreign Relations Committee said Sunday.

“The killing of Osama bin Laden closes an important chapter in our war against extremists who kill innocent people around the world," Sen. John Kerry (D-Mass.) said in a statement.  "We are a nation of peace and laws, and people everywhere should understand that our ten-year manhunt was in search of justice not revenge."

"Terrorists everywhere must never doubt that the United States will hunt them down no matter where they are, no matter how long it takes," Kerry said.

Kerry praised the American military and intelligence communities "for their tireless dedication and enormous sacrifice to bring justice to a man responsible for the deaths of nearly 3,000 Americans on September 11 and thousands more men, women, and children around the world."

He also commended President Obama and the Obama administration's national security team. Kerry warned though that bin Laden's death did not mean the end of terrorist threats around the world.

“A single death does not end the threat from al Qaeda and its affiliated groups. We must remain vigilant and committed to keeping the world safe and secure.”
