On this day 20 years ago, al-Qaeda* terrorists hijacked four commercial planes. Two of the planes were flown into the World Trade Centre towers in New York. Another plane struck the west side of the Pentagon, and yet another one crashed in Pennsylvania before reaching its presumed target. Nearly 3,000 lives were claimed in the attacks.
*Al-Qaeda is a terrorist organisation banned in Russia and many other nations.
