9/11 remembered – seven years on

Memorial ceremonies are underway to mark the seventh anniversary of the September 11 terrorist attacks on the United States.

As usual, much of the focus is on New York where the World Trade Center collapsed. White House rivals Barack Obama and John McCain were due to lay wreaths at Ground Zero. There and at other sites of the mass killings, the names of the nearly 3,000 victims were being read out.

In Washington, President George W. Bush observed a moment’s silence at the White House.

On September 11 2001, four hijacked planes crashed into the Twin Towers in New York, the Pentagon in Washington and a field in Pennsylvania.

US officials blame al Qaeda whose leader Osama bin Laden has boasted of organising the attacks.
