International transport trucks are blocked two kilometres from the border crossing of Promachonas between Greece and Bulgaria, in northern Greece, as farmers set up a blockade at customs offices, shutting down the movement of trucks to and from Bulgaria on February 7, 2016.
Greek farmers protesting against pension reforms heightened highway and border protests around the country, piling pressure on the leftist government of Prime Minister Alexis Tsipras. The mobilisation which began in mid-January has created tractor blockades at dozens of highway locations and key border crossings to Bulgaria and Turkey, which the farmers intermittently open for a few hours each day. / AFP / SAKIS MITROLIDIS        (Photo credit should read SAKIS MITROLIDIS/AFP via Getty Images)
