Eyewitnesses say the archduke was sitting upright while his wife slumped forward.

Officials have confirmed that the archduke and his wife have been taken to the Konak, the official residence of Governor Oskar Potiorek. There is still no word about their condition.

The suspect arrested in the earlier bomb attack, Cabrinovic, has told police that the bomb was acquired from an unspecified "organisation". He has refused to give any further details or reveal whether he was part of a coordinated assassination plot.

Police have named the suspect as Gavrilo Princip.

It is not known if the two attacks are linked.

A police officer is reported to have been injured during the arrest of Princip.

An eyewitness, Danilo Pusili, was standing near the archduke's car at the time of the shooting.

Pusili claims to have grabbed hold of the assassin's collar in the aftermath, saying: "I thought of strangling him, but then, I thought of my Eternal Judge, and rejected the temptation".

A spectator who was a guest at City Hall earlier described the archduke as striding boldly into the building, but that he seemed "strange", adding, "I suppose he was trying to show that he was not afraid".

Questions will surely be asked about the security operations for today's trip.

When Emperor Franz Joseph visited Sarajevo in 1910, security is reported to have been much tighter than during today's visit. Soldiers lined the route and all newcomers to the city had to register within six hours of their arrival.

We have just heard from the Archduke's aide, Count Frank Harrach, who was standing beside the archduke when the attack took place.

He has revealed details of the archduke and Sophie's final moments.

After the shots were fired, Harrach describes seeing "a thin stream of blood spurt from His Highness's mouth onto my right cheek". As Harrach went to the archduke's assistance, the duchess appears to have cried out, "What has happened to you?" before sinking down in her seat with her face between her knees.

"I had no idea that she was hit and thought she had simply fainted with fright. Then I heard His Imperial Highness say, 'Sopherl, Sopherl, don't die. Stay alive for the children!'"

Lt Col Harrach added "I seized the Archduke by the collar, to stop his head dropping forward, and asked him if he was in great pain. He answered me quite distinctly, 'It's nothing!'

"His face began to twist somewhat but he went on repeating, six or seven times, ever more faintly as he gradually lost consciousness, 'It's nothing!' Then, after a short pause, there was a violent choking sound caused by the bleeding. It was stopped as we reached the Konak."

The bodies of the archduke and duchess will remain for the time being at the Konak. There are no further details at this stage.

Flags are being lowered to half mast across the city.

News of the Archduke's death spreads across Europe during the afternoon.
