A woman watches the Tribute in Light illuminated on the skyline of lower Manhattan during events marking the 13th anniversary of the 9/11 attacks on the World Trade Centre in Jersey City, New Jersey, US, earlier this week. Until a few months ago, the part of New York City where crowds gathered on Thursday morning to mark the 13th anniversary of the September 11 attacks had been mostly fenced off to the public. This year, for perhaps the first time since the attacks, a sense of normality and openness has taken root in the city blocks where two airliners hijacked by militants from al-Qaeda crashed into the World Trade Centre’s twin towers.
