Prime Minister Antonis Samaras travelled to France to attend, along with 50 other leaders, the march against terrorism which began shortly after 15.00 local time. The PM stood with other leaders and officials in the human chain, sending a clear message that everyone is united in the fight against terrorism after the massacre at the offices of satirical newspaper Charlie Hebdo, the deadly attack on a police officer and the hostage situation in the Jewish grocery store.
