Victims of the 9/11 attacks and their families are entitled to big tax breaks, but many are missing out because the IRS isn’t telling them about the benefit. Under a law passed months after the attacks, disability income resulting from terrorism is not taxable. That means thousands of cops, firefighters and other first responders sickened after working at the site, and the families of those who’ve died, can claim $10,000, or the last three years of taxes the victim paid, whichever amount is larger.

The number of first responders suffering from cancer after inhaling 9/11 fumes has more than doubled since last year, according to a new report. Some 1,655 cops, city workers, volunteers and locals exposed to toxins from the collapse of the World Trade Center have been diagnosed with the deadly disease, according to Mount Sinai Hospital's World Trade Center Health Program, which tracks the health of 37,000 first responders.

A military judge ruled Thursday that one of the five defendants being tried at Guantanamo Bay, Cuba, for their alleged roles in the Sept. 11, 2001, attacks be severed from the proceeding. The decision delivers another in a series of delays to the government’s effort to prosecute Ramzi Binalshibh, a Yemeni described as a key figure in the plot who acted as a liaison between the hijackers and al-Qaeda’s leadership in Afghanistan.

The terrorist threat against the U.S. remains dangerous 10 years after the 9/11 Commission issued its first report -- only now the risk is greater online. In a report issued today, panel members who studied the 2001 attacks urge Congress to enact cybersecurity legislation, the White House to communicate the consequences of potential cyber-attacks to Americans, and leaders to work with allies to define what constitutes an online attack on another country.

The global struggle against terrorism has "entered a new and dangerous phase" with growing threats posed by foreign fighters returning from the civil war in Syria and the vulnerability of critical systems to cyber attack, the original authors of the 9/11 Commission report concluded in a new analysis. Marking the 10th anniversary of the panel's landmark report, which identified an array of intelligence failures leading up to the 2001 terrorist attacks, panel chairman Tom Kean said Tuesday there was "broad agreement" on the new threats facing the nation and rest of the world.

Vice President Joe Biden paid special tribute to the 9/11 generation during his address to more than 12,000 members of the Veterans of Foreign Wars at the organization’s national convention in St. Louis yesterday. Biden singled out former Army Sgt. Ryan Pitts, who received the Medal of Honor at a White House ceremony later in the day for his actions against more than 200 heavily armed insurgents near a small Afghanistan village in 2008. More.

On a recent afternoon, an older man and woman self-consciously configured themselves in front of the south reflecting pool at the 9/11 Memorial. The man placed his hand on the woman’s hip in an awkward clasp and grinned broadly as another person took their picture with a digital camera. A girl in a Yankees cap took a selfie with her camera phone, the Freedom Tower soaring into the sky behind her, the reflecting pool draining into nothingness. She was smiling. More.

Last month, Department of Transportation (DOT) and District of Columbia transportation officials met with local residents to discuss the proposed tunnel expansion in Washington, DC by CSX Corporation, one of the nation's leading rail and intermodal transportation companies. Residents criticized the government officials and CSX for lack of transparency. More.
