Ceremonies are taking place across Europe to mark 100 years since the outbreak of World War I.
Fifty heads of state gathered in Belgium to remember the German invasion, and Britain's declaration of war on Germany.
It was also supposed to be “the war to end all wars,” but a hundred years later, tensions in Europe are ratcheting up yet again, particularly between Russia and the West.
One country that is close to both sides is Serbia: a traditional ally of the Kremlin that is also looking to join the European Union.
“No one needs any more crisis in the heart of Europe,” Serbian Prime Minister Aleksandar Vucic told CNN’s Fred Pleitgen, in for Christiane Amanpour, on Monday. “No one needs any more problems, any more clashes, any more fights.”
“And we are doing our best to be a pillar of that stability in this region. We do our best to improve our economy. We do our best to be a modern state.”
‘As you know, Serbian guy triggered that First World War, Gavrilo Princip,” Prime Minister Vucic said. “That's the reason that … we are striving for peace … not to cause any more problems; not to be a part of the problem, but to be a part of the solution; to be a part of creating a modern state, to creating the best possible environment in the whole region.”
