A PLAN by a group of peace campaigners to travel by bus to Baghdad to offer themselves to Saddam Hussein as human shields has been threatened with collapse by the personal clashes, logistical chaos and the loss of their leader.

One of the group’s three double-deckers has been abandoned in Italy with engine trouble and plans to travel through the Balkans were aborted as “too dangerous”. The head of the delegation, a former American marine, has been deported from Turkey for trying to enter the country with a “world citizen” passport after renouncing his United States citizenship.

The second of the two remaining red buses and an accompanying white taxi limped into Istanbul yesterday after being stranded in blizzards for two days. Several members of the peace convoy spent the day scrabbling around the Turkish city trying to hire four-wheel-drive vehicles or trying to book plane or train tickets to take them on to Baghdad. “There comes a time at which we have to leave the buses behind and move on without them,” said John Rose, an American who spent seven years with the Zapatista rebels in Mexico and has joined the trip in Turkey. “We just have to cut them loose now.”

Yesterday the dwindling group of 40 “peaceniks” was joined by 35 Turkish volunteers. There was also a shock. Organisers told the human shields they must each stump up $1,000 before they could enter Iraq. In addition, they would have to leave their mobile phones at the border, cutting off all communication with home, and be subjected to tests for HIV.

Helen Williams, 34, from Newport, south Wales, said funds were already running dangerously low. “Some people are getting down to their last few pounds,” she said. “The sooner we get to Baghdad where we can live more cheaply, the better.”

Rajia Dhanjani, a 22-year-old hairdresser from south London, said: “I thought it would be hard when we got to Baghdad, but I had no idea the trip would be this awful. I thought the journey would be one long party.”

Last night the group held a crisis meeting at a cafe in Istanbul. The Turks showed themselves determined to impose more efficient organisation on the ramshackle British expedition which arrived almost a week behind schedule.

After three hours of debate, the Turks won through. The convoy will now remain in Istanbul until tomorrow.

“We have to show we are together on this,” said Tolga Temuge, 36, a Turk who quit his job as campaigns director of Greenpeace in the Mediterranean to travel to Iraq.

The British contingent were keen to strike out today for Ankara before heading to Syria en route for Jordan and then Iraq. However, the Turks, shocked at the shambolic antics of the British, pushed for a delayed departure to allow time to regroup.

The two red London buses, the white taxi and two minibuses will now head for Ankara tomorrow. Volunteers are trying to switch their minds from the disarray of recent days to the situations they will face on arrival in Baghdad, assuming they get there.

One of the buses, however, may have to find a new driver soon. Its driver, who identifies himself only as Gary, said the Syrian authorities had told him he would not be permitted to drive his vehicle through their country because his mother works for the Ministry of Defence in Britain.

If Gary’s mother’s job has made his journey difficult, his place in the convoy has been of little help to his mother. “My mum has had a really hard time because of me,” he said. “She works in intelligence and she has been blackballed by the ministry ever since they found out I was on the trip.”
