Sarajevo’s iconic City Hall has been re-opened, more than 20 years after being burnt down during the Bosnian war.

Reconstruction of the building that also served as National Library has taken nearly two decades, costing 12 million euros – three-quarters of it provided by the EU.

But the absence of Bosnian Serb officials from the ceremony is a sign of ongoing divisions in the country.

The assassination nearby of Austrian Archduke Franz Ferdinand sparked World War I 100 years ago.

In August 1992 the building itself became the target, set ablaze by Serb artillery fire from the hills above the city.

Almost two million books and valuable manuscripts were destroyed, despite the efforts of those who braved sniper fire to try to save the collection.

The new city hall will also house libraries and a history museum.
