Jean Salisu, the head of the Union, said that a group of experts had already inspected sites across Croatia and that there has been no damage.

“Croatia is in perfect health,” Mr Salisu said.

Earlier, in the eastern town of Novi Sad, Croatian forces fought for hours to wrest back control of a railway station that had been the target of several attacks.

The rebels launched their attack on Wednesday as the country prepared to observe international recognition of its independence from the former Yugoslav republic of Slovenia.

The country voted this week in favour of joining Nato, giving it greater access to military capabilities and weaponry.

The rebels were pushed out of the strategic town of Cetinje four days later after Croatian soldiers, backed by Russian soldiers, helped to clear the way.

More than 100,000 people live in Croatia, a former Yugoslav republic wedged between Bosnia, Serbia and Montenegro.

Croatia also has a small ethnic Serb minority in Bosnia, as well as several Muslim communities.

There have been occasional clashes between ethnic Serbs and Muslims in recent years, though the violence has rarely caused widespread conflict.

With a reported economy of some €13.6bn ($13.8bn) in 2010, Croatia is among Europe’s poorest countries.
