Two hundred people protesting against the war in Iraq have scuffled with police in Sydney ahead of the arrival of Dick Cheney, the US vice president, in Australia.
A police spokeswoman said seven people were arrested when police barred up to 200 members of the Stop the War Coalition from marching through Australia's largest city.
The protesters demanded that John Howard, the Australian prime minister, pull out the 550 Australian troops based in Iraq.
The demonstrations came just a day after Denmark and Britain, two of the US's main allies in Iraq, announced plans to withdraw many of their troops.
Heavy police presence
A heavy police presence, including officers mounted on horseback, ringed the protesters in an attempt to minimise disruption to peak-hour commuters, some of whom also squabbled with police.
Protesters held placards saying "Dick Go Home & Take John With You" and "Coalition of the Killing".
Police later relented and shepherded protesters as they marched towards the US consulate. Another protest is planned for Friday.
Cheney arrived amid tight security several hours later. He is to meet Howard on Saturday.
Howard has ruled out following Britain's example and cutting troop numbers in Iraq, but his unwavering commitment has him walking through a political minefield towards an election later this year.
British pullout
Cheney's trip to Australia is meant to reassure Washington's allies that Bush's planned injection of 21,500 more troops into Iraq will help quell violence.
But Britain's promise to soon start withdrawing troops has added to the pressure on Washington's other allies.
Denmark and Lithuania have said they would pull out their much smaller commitments.
"Out of Step," the Sydney Morning Herald said in a front-page headline about Australia's Iraq commitment.
Iraq is a major problem for Howard's conservative government ahead of elections in the second half of 2007, perhaps the toughest of his 11-year tenure.
An opinion poll this week found 67 per cent of Australians either want Howard to set a date for withdrawing troops from Iraq or pull them out immediately.
