Today is the 16th anniversary of 9/11 attacks in the US. This was the deadliest terror attack on US soil to date since the bombing of Pearl Harbor by the Japanese. The attack claimed the lives of 3,000 people and 16 years later, the US is yet to fully move on from this tragedy.

We have compiled a few photos that try to explain the events of this day. Take a look below.

It was a normal morning in New York. The Twin Towers stood high in the sky and it appeared to be business as usual.

At about 8:46 in the morning, the first plane hit the towers. This was the American Flight 11 which hit the North Tower. At this point, it was not yet clear whether this was an attack or an accident.

The final plane crashed in the Pennsylvanian town of Shanksville. This was the United Flight 93 which was believed to have been heading to the Capitol. Passengers in the plane regained the aircraft from the terrorists after getting wind of the three attacks that had so far rocked the nation.

It was 10:28 AM and just like the South Tower in New York, the North Tower couldn’t hold either. It went down completely in 12 seconds. The devastation caused by these attacks was now becoming clear. About 2,753 people were confirmed dead in New York and 343 firefighters were among the dead. Paramedics too suffered the devastation as well as additional 60 cops from the city. The death toll rose as 183 people were confirmed dead in Washington and 40 others in Pennsylvania. About 3,000 fatalities in total. The US was in shock.
