Chinese embassy warning ignored
The embassy bombing sparked widespread protests against Nato
Three days before Nato bombed the Chinese embassy in Belgrade, a military intelligence officer told colleagues the wrong building had been chosen, US officials have revealed.
The bombing - described as a "tragic error" by Nato - sparked angry demonstrations in China, where most people accused Nato, and the US in particular, of deliberately targeting the embassy.
On Thursday Pentagon officials confirmed the reports, originally made in the Washington Post newspaper.
Officer had doubts
The analyst did not know the building in question was in fact the Chinese embassy.
Despite repeated US apologies, the bombing has severely damaged Chinese-American relations.
String of errors
It now appears the bombing was caused by a litany of mistakes.
First, CIA staff were using outdated maps and databases which did not show the embassy had moved to a new location.
Then an analyst made a mistaken assumption about the FDSP's location based on its address.
The Washington Post's diplomat correspondent, Steve Merson, told BBC Radio 5 Live he literally "put the X in the wrong spot".
Even then the situation was not lost. A second analyst noticed discrepancies between the FDSP's supposed location and that of the target building.
Failed to get hold of CIA
But he failed to arrange the meeting at the CIA.
He then went off for scheduled training and when he returned on 7 May he found the raid was planned for that night.
The Washington Post says there is confusion about who he rang to raise his concerns but at one point he was apparently told: "The bombers are in the air. It's too late".
US officials say the analyst was not involved in selecting the target, but took an interest because he had some knowledge of the FDSP.
Mr Bacon said the Pentagon was reviewing what happened as part of a broader review of targeting decisions.
White House spokesman Joe Lockhart said the CIA would also conduct a review of accountability.
