US commemorates 18th anniversary of September 11 terror attacks

Americans are commemorating 9/11 with mournful ceremonies, volunteering, appeals to “never forget” and rising attention to the terror attacks’ extended toll on responders.

A crowd of victims’ relatives is expected at ground zero Wednesday, while President Donald Trump is scheduled to join an observance at the Pentagon. Vice President Mike Pence is to speak at the third attack site, near Shanksville, Pennsylvania.

Former President George W. Bush, the commander-in-chief at the time of the 2001 attacks, is due at an afternoon wreath-laying at the Pentagon.
