Two men have been killed after guards working for the Swiss biotech company Syngenta clashed with activists invading a genetically modified (GM) seed farm in Brazil. This is the latest in several such protests by the Landless Workers' Movement (MST) in Brazil targeting multinationals in the agribusiness sector and what it sees as the "evil effects of genetically modified products"...The MST accused Syngenta of hiring security services that were used to form armed militias to evict and attack landless settlers. In a statement, Syngenta denied claims by the MST it had ordered the use of force, adding that its guards work unarmed by contract...While Brazil's national government allows use of GM seeds for some crops, Parana's state government recently outlawed GM corn and has tried repeatedly to shut down the Syngenta farm.
