Donald Trump warns 'America cannot be intimidated' as US remembers 9/11

President Donald Trump, leading his first commemoration of the 9/11 anniversary, has said "the living, breathing soul of America wept with grief" for each of the nearly 3,000 lives that were lost on that day 16 years ago.

Addressing an audience at the Pentagon, one of three sites attacked on September 11 2001, Mr Trump used the anniversary to sternly warn terrorists that "America cannot be intimidated".
