Bus owners and drivers in Bolivia are holding a 24-hour strike in protest at an unexpected government decision to cut subsidies for petrol and diesel.
The strikers blocked roads and stopped transport services in two of the main cities, La Paz and Cochabamba.
Other trade unions and social groups in Bolivia are also considering protests over the government's move, which will lead to price rises of at least 10%.
The government says the subsidies are financially unsustainable.
It also says they allow Bolivians to resell fuel abroad illegally.
The organisers and the government have argued over the amount of support each claims the strike has received.
