Today marks the 13th anniversary of September 11 terrorist attacks against the United States.  It was on this day in 2001 that al Qaeda hijackers flew planes into the World Trade Center towers in lower Manhattan as well as the Pentagon building in Washington D.C.

A fourth plane crashed in a field in Shanksville, Pennsylvania, after passengers and crew rushed the cockpit.  Nearly 3,000 people were killed that day, including all 19 hijackers.  It was the deadliest terrorist strike on U.S. soil.

Ceremonies and exhibits have been planned across Michigan to mark the anniversary of the September 11th terrorist attacks.

Governor Rick Snyder is scheduled to be the guest speaker at the Michigan Fallen Heroes Memorial in Pontiac.

A ceremony is also planned at Muskegon Museum of Art.  It marks the opening of an exhibit called "Remember and Rebuild," which tells the story of the creation of the National September 11 Memorial Museum in New York and runs through November 9th.
