In rather a bizarre change of plans, Colin Powell has cancelled his visit to Athens; he cited "urgent responsibilities".
It seems he will visit later in the year instead.
Last night police fought running battles with demonstrators, as they attempted to march without success to the US embassy.
Prior to this announcement, demonstrators had managed to breach security by hanging a large banner on the Acropolis, in front of CNN, saying: "Powell, killer, go home".
Whilst the anti USA demonstrators will doubtless be crowing about their "success" in driving Powell away; the rumour is that Powell was persuaded by the Greek authorities not to come, for fear of provoking a PR and security debacle.
