NEW YORK (Reuters) - Relatives assembled under overcast skies on Friday to commemorate nearly 3,000 people killed in the Sept. 11 attacks in New York, Pennsylvania and outside Washington 14 years ago, when airliners hijacked by al Qaeda militants brought death, mayhem and destruction.

In New York, families of the victims read their names in a solemn and poignantly familiar pattern, watched over by service members in their dress uniforms.
