The removal of the Soviet monument in April led to violent clashes

Russian diplomats shunned the ceremony, despite an official invitation from the Estonian government.

The exhumation of the remains in April and the removal of a Soviet war memorial led to two nights of clashes between ethnic Russians and police.

It also caused a rift in ties between the two countries and led protesters to blockade of Estonia's Moscow embassy.

The memorial has also been re-located to the military cemetery, outside the city centre.

Russia's embassy said it would attend a separate ceremony at the cemetery after the official re-burial was over.

At the time of the row, Moscow described the removal of the statue as a "blasphemous" insult to those who died fighting Nazism.

For many Estonians the Soviet war memorial is a painful symbol of decades of communist rule from Moscow.
