HELENA, Mont. (AP) — Montana emergency responders and political leaders marked the 17th anniversary of the Sept. 11 terror attacks with a ceremony in the state Capitol.

Gov. Steve Bullock, U.S. Rep. Greg Gianforte and Attorney General Tim Fox were among the speakers Tuesday who remembered the first responders who died in 2001 and paid tribute to local firefighters and emergency personnel.

Helena Mayor Wilmot Collins called for people to unite and said that "fellow Americans will never be our enemy."

The ceremony was capped by the ringing of a bell to honor fallen firefighters and bagpipes playing "Amazing Grace."

Nearly 3,000 people died when terrorists flew airplanes into New York's World Trade Center, the Pentagon and a Pennsylvania field on Sept. 11, 2001.
