Pentagon: US-led strikes help rebels retake city

A barrage of US-led airstrikes opened the door for Libyan rebels to retake the eastern city of Ajdabiya Saturday, handing President Barack Obama a tangible example of progress as he defends the military action to war-weary Americans. Obama cited "significant success" in the war Saturday, and he and others defended the US intervention as lawful and critical to save thousands of lives and stabilize a strategically vital region in the Middle East.

"The United States should not and cannot intervene every time there's a crisis somewhere in the world," Obama said in his weekly radio and Internet address Saturday. But with Libyan leader Muammar Gaddafi threatening "a bloodbath that could destabilize an entire region ... it's in our national interest to act. And it's our responsibility. This is one of those times." (AP)
