Protesters carrying a model bulldozer snaked through the streets of Brighton to protest at the treatment of Palestinians.

The campaigners were urging people to boycott goods made by American firm Caterpillar, which they say is the chief supplier of military bulldozers to Israeli forces.

Members of the Brighton and Hove Palestine Solidarity Campaign demonstrated following the death of an American peace protester under a bulldozer in the Occupied Territories last month.

Rachel Corrie's death was witnessed by Sussex Action for Peace activist Richard Purssell while they both worked with the International Solidarity Movement.

Organiser Chris Osmond said the event was a piece of street theatre to make people aware of the situation, particularly shops stocking Caterpillar shoes and jackets.

A statement released by the firm last year reads: "While we have compassion for all those affected by the escalating political strife, we have neither the right nor means to police customer use of Caterpillar equipment.

"Comments on the political conflict in the region are best left to our governmental leaders, who have the ability to advance peace."

In the first half of 2002 the firm, based in Peoria, Illinois, reported sales of $9.7 billion.

On its web site, the company states: "Caterpillar accepts the responsibilities of global citizenship. Wherever we conduct business or invest resources, we know our commitment to financial success must also take into account social priorities."
