Families of the victims of the 9/11 attacks in New York have paid tribute to their loved ones during a ceremony at Ground Zero. It is 11 years ago today that nearly 3,000 people died in the atrocity. President Obama led the memorial at Washington.
US President Barack Obama has told 9/11 victims' families that the whole country shares their loss on the 11th anniversary of the terrorist attacks.
Speaking at the Pentagon, where 184 people were killed, Mr Obama said:
Eleven times we have paused in remembrance and reflection, in unity and in purpose. This is never an easy day, but it is especially difficult for all of you, the families of nearly 3,000 innocents who lost their lives.
But no matter how many years pass, no matter how many times we come together on this hallowed ground, know this: That you will never be alone, your loved ones will never be forgotten.
They will endure in the hearts of our nation because through their sacrifice they helped us make the America we are today, an America that has emerged even stronger.
The 70,000 surviving firefighters, police officers and other first responders who raced to the World Trade Center after the attacks on September 11th, will be entitled to free monitoring and treatment for some 50 forms of cancer.
While other illnesses have long been covered by a compensation scheme, there has been a long debate over including cancers.
The National Institute for Occupational Safety and Health has said that responders as well as survivors exposed to toxic compounds from the wreckage, which smoldered for three months, will be covered for cancer under the Zadroga 9/11 Health and Compensation Act.
Illnesses related to the attacks have caused an estimated 1,000 deaths. Last week, the New York City Fire Department etched nine more names into a memorial wall honouring firefighters who died from illnesses after their work at Ground Zero, bringing the total to 64.
