A physically disabled woman on her wheelchair clashes with riot police in the centre of La Paz.

La Paz, Bolivia - Protesting disabled people have clashed with police in Bolivia's capital during a demonstration demanding that the South American country's government pay them an annual subsidy.

A caravan of about 50 adults and children, some using crutches, others in wheelchairs, arrived in La Paz on Thursday after a 100-day protest journey, then clashed with riot police guarding the legislature.

At least four people have been detained and the windshield of a police car broken as the protesters banged on police shields trying to break into the legislature.

The group began it's protest trip to demand that Bolivia's government pay disabled people at least 3 000 bolivianos a year. That is just over $430. - Sapa-AP
