Prime Minister Kyriakos Mitsotakis voiced anger at Tuesday morning’s arson attacks on property linked with three of his conservative New Democracy party officials in Thessaloniki that injured five people, one gravely.

In a speech to ND lawmakers, Mitsotakis promised “zero tolerance” for terrorists, adding that he would travel to the northern port city to meet the officials and be briefed on the condition of the injured.

“I must express my shame and anger at the cowardly, terrorist, murderous attack,” he said. “There will be zero tolerance for any new form of terrorism … We have left these times behind us.”

Greece suffered from political violence for decades, mainly from armed far-left groups, while far-right attacks linked with the Nazi-inspired Golden Dawn party emerged in the first years of the country’s 2009-2018 financial crisis.

The most murderous group, far-left November 17, active since 1973, was eradicated in 2002 and a series of smaller far-left – mostly anarchist – groups that tried to continue in its steps have long been broken or out of action.
