Yesterday was the 10th anniversary of 9/11.
“9/11” refers to three terrorist attacks in the United States that occurred on September 11, 2001 – the ninth month, the 11th day.
On that day 10 years ago, nearly 3,000 people were killed when terrorists attacked two World Trade Centre buildings in New York and the Pentagon in Washington DC. Near Pennsylvania, a plane was hijacked and crashed into a field.
The victims of the attacks were from more than 90 countries. Around the world, millions of people commemorated 9/11 in their own way.
At the site in New York where the twin towers once stood, called Ground Zero, thousands of people attended remembrance services.
