President Obama Set to Observe 9/11 Anniversary VOA News 11 September 2010 U.S. President Barack Obama will join Defense Secretary Robert Gates at the Pentagon, the U.S. military headquarters, on Saturday for a memorial service marking the ninth anniversary of the September 11, 2001, terrorist attacks. In his weekly address, President Obama designated Saturday a National Day of Service and Remembrance to honor the nearly 3,000 people who lost their lives.  Mr. Obama said if there is any lesson to be drawn on the anniversary, it is that the United States is one nation and one people united by common ideals. He also said by serving people in need, Americans reaffirm their ideals in defiance of those who would harm the United States.  In New York, the names of the 2,752 people who died in the attacks will be read out loud by family members. There will also be moments of silence when the first hijacked plane and then the second struck the twin towers of the World Trade Center, and then later marking the times when the two buildings collapsed. Events are being held across the country to honor the victims. The official commemoration in New York will be attended by Vice President Joe Biden while first lady Michelle Obama and former first lady Laura Bush are traveling to Shanksville, Pennsylvania, where the fourth hijacked plane crashed. In the weekly Republican address, Senator Jon Kyl of Arizona, said it is important to differentiate between militant Islamist ideology and the Muslim faith practiced by more than one billion people around the world. President Obama said the search for Osama bin Laden, the al-Qaida leader considered the mastermind of the attacks, remains a high priority, as well as locating al-Qaida's second-in-command, Ayman al-Zawahiri. He said the United States has been successful in increasing pressure on both men, forcing them to go further underground. .
