U.S. Consulate in Jerusalem Issues 9/11 Anniversary Security Message

Americans plan solemn ceremonies for 12th anniversary of September 11 attacks.

The U.S. Consulate in Jerusalem called on American citizens in Israel to exercise caution during the 12th anniversary of the September 11 attacks.

"As the anniversary of the 9/11 attacks approaches, the U.S. Consulate in Jerusalem reminds U.S. citizens of the need for caution and awareness of personal security," a security message published on Tuesday said.

U.S. citizens were asked to "remain aware of your surroundings, including local events" and monitor local news for updates.

The consulate said it has limited official travel by government employees in the West Bank on Wednesday, excluding Bethlehem and Jerico.

Those planning to travel to Israel, Gaza and the West Bank were requested to sign up online for the State Department's Smart Traveler Enrollment Program, which provides security updates and is available online.

U.S. remembers September 11 victims

Americans will commemorate the 12th anniversary of the September 11 attacks with solemn ceremonies and pledges to not forget the nearly 3,000 killed when hijacked jetliners crashed into the World Trade Center, the Pentagon, and a Pennsylvania field.

New York City, still scarred from the attacks that brought down the Twin Towers, will repeat the ritual of reading of the names of the 2,983 people who died at the World Trade Center, the Pentagon and a field near Shanksville, Pennsylvania.

A citywide moment of silence will be held at 8:46 A.M. (1246 GMT) in observance of the time American Airlines Flight 11 crashed into the North Tower, followed by another at 9:03 A.M. (1303 GMT) when United Airlines Flight 175 struck the South Tower.

Further moments of silence will be observed at 9:37 A.M. (1337 GMT), when American Airlines Flight 77 hit the Pentagon; at 9:59 A.M. (1359 GMT) when the South Tower fell; at 10:03 A.M. (1403 GMT) when United Flight 93 hit the ground near Shanksville; and at 10:28 A.M. (1428 GMT) when the North Tower collapsed.

The ceremony will be held at the National September 11 Memorial plaza, where two reflecting pools mark the footprints of the original Twin Towers.

In Washington, U.S. President Barack Obama will attend a Pentagon ceremony with Secretary of Defense Chuck Hagel and Chairman of the Joint Chiefs General Martin Dempsey. The private ceremony at the Pentagon Memorial includes a wreath-laying and is for family members of those killed in the attack.

Hagel and Dempsey will attend a second ceremony later in the Pentagon's center courtyard.

At the Flight 93 National Memorial in Pennsylvania, the National Park Service was holding a groundbreaking for the visitor center on Tuesday and a memorial service on Wednesday starting at 9:45 A.M. that will include a reading of the names of the Flight 93 passengers and crew, a ringing of bells, a wreath-laying, and brief remarks.

A number of cities will hold ceremonies including 21-gun salutes, moments of silence, and memorial services on Wednesday to remember those who lost their lives including the police officers and firefighters killed working to save the victims of the attacks.

The website 911memorial.org is encouraging classroom discussions, service projects, and other commemorative acts.
