Charlie Hebdo massacre, which took place on January 7, was the first in a
series of terrorist attacks in Paris. On January 8, a female police
officer was shot dead by a gunman in the Paris suburb of Montrouge. The
following day, the suspected gunman killed four hostages in a kosher
supermarket.
On January 11, over 3 million people, including around 40 world leaders,
have gathered on the streets of France commemorating the victims of
three consecutive terrorist attacks that struck the country January 7-9.
