On September 11th, 2001, two hijacked planes rammed into the north & south tower of the World Trade Center in what was one of the most horrific terrorist attacks in history. The world watched on in horror as the two powerful structures crumbled and were reduced to rubble. Around 3,000 people died. Mankind had faced a big challenge, but the challenge was answered by prayers and tributes for the ones who lost their lives that day. These 14 emotional photos show some of the best tributes paid to the victims:
