(CNN)Just two weeks shy of the 30th anniversary of the fall of the Berlin Wall, an election in the east German state of Thuringia has highlighted the deep divisions still gripping the country.
How a former history teacher led a far-right surge in eastern Germany
Centrist parties -- including Chancellor Angela Merkel's conservative CDU -- were bumped into third place after the left-wing Die Linke and far-right Alternative for Germany (AfD) surged ahead.
Incumbent Die Linke took top spot with 31% of the vote, a slight increase on the last state election five years ago.
But it was the phenomenal rise of the AfD, which came in second place with 23.4% of the vote, that raised serious concerns, particularly among Jewish leaders, in the wake of a shooting outside a synagogue earlier this month.

Even within his own party, Höcke has faced criticism for his radical views, Klautke added.
Thuringia's election comes at a delicate time in German politics, just weeks after a far-right attacker went on a shooting rampage outside a synagogue in the eastern town of Halle.
Höcke condemned the Halle attacks. But his party was nonetheless accused of inciting a culture of hatred by Charlotte Knobloch, president of the Jewish community in Munich.
Following the AfD's success in Thuringia, Knobloch warned on Twitter that its voters had "supported a party that has been preparing the ground for marg
