CNN: “Osama bin Laden, the mastermind of the worst terrorist attacks on American soil, is dead, officials said — almost 10 years after the attacks that killed about 3,000 people. The founder and leader of al Qaeda was killed by U.S. forces Monday in a mansion in Abbottabad, north of the Pakistani capital of Islamabad, along with other family members, a senior U.S. official told CNN. In an address to the nation Sunday night, U.S. President Barack Obama called bin Laden’s death “the most significant achievement to date in our nation’s effort to defeat al Qaeda.”
