Argentina farmers strike

A strike by Argentina farmers over rising taxes on major export goods has entered its third week, with little sign of resolution.

Blockades by farmers have led to shortages in the shops and have also hit exports, with some companies saying they cannot fulfill their contracts.

The government said the tax increases are justified and it will use force if necessary to get food to the markets.

Rival demonstrators reportedly rallied in Buenos Aires overnight amid some scuffles.

The latest crisis was sparked by the government\'s decision to introduce a new sliding scale of export taxes, raising levies in some cases up to 45 percent.
