One of the first sights that greets arrivals to the centre of Serbia's capital Belgrade are government buildings in an advance state of collapse. Nato planes bombed them back in 1999 – and they remain in much the same condition.

The message they deliver to visitors could be "welcome to Serbia, our recent history has been tumultuous and complicated – and we still haven't quite finished processing it".

Like a smile with a row of broken teeth, the Defence Ministry buildings are still standing. But they clearly took a serious hit when Nato intervened to stop Serbia's then military campaign in Kosovo.

As a member of the Western military alliance, the US was implicated in the bombing.

Given that history, last year it came as something of a jolt for Serbians when the government struck a deal with a company called Affinity Global to redevelop the site into a $500m (£370m) luxury hotel and apartment tower complex.
