Captured: one of the world’s most wanted men

Details were still emerging this morning of the capture in Serbia of Radovan Karadzic, the Bosnian Serb war leader variously described as one of the world's most wanted fugitives and - by Richard Holbrooke, who negotiated the 1995 Dayton accords that ended the war in Bosnia - as "a true architect of mass murder".

Thirteen years after being indicted by the UN war crimes tribunal on genocide charges for his role in Europe's worst atrocity since World War Two - the 1995 massacre of more than 8,000 Muslim men and boys at Sebrenica - 63-year-old Karadzic was finally arrested on a bus outside Belgrade by Serb security forces.

It appears he has been practising alternative medicine in a clinic in Belgrade. He sported a long white beard (right) and called himself Dragan Dabic. His landlord claims to have had no idea of his true identity.

Karadzic will now be transferred to The Hague where he faces charges including genocide, extermination, murder, willful killing, deportation and inhumane acts. As well as orchestrating the Srebrenica horror, he is charged with organising the 1992-96 siege of Sarajevo in which 12,000 died.

His capture comes after European governments have piled pressure on the new government in Belgrade to cooperate with the war crimes tribunal if it wants progress towards Serbian membership of the EU.

The appointment only last week of a new head of Serbian Intelligence, Sasha Vukadinovic, is also significant. It seems likely that members of the security services knew all along where Karadzic was hiding, and finally gave him up.

The question now is whether they can also produce Karadzic's henchman, the Bosnian Serb army commander, Gen Ratko Mladic, the man who directly ordered the killings at Srebrenica. He remains at large - according to some reports, protected by elements of the Serbian army.
