From the Guardian:

RIO DE JANEIRO, Brazil (AP) - Hundreds of loggers and angry residents have surrounded eight Greenpeace members who tried to leave an Amazon town with a scorched tree trunk for an exhibit on global warming, the environmental group said Wednesday.

The activists are holed up in the makeshift headquarters of the federal environmental agency in the town of Castelo dos Sonhos, Greenpeace campaigner Andre Muggiati said. "They are still surrounded and the situation is tense,'' he said by telephone.

The region in the Amazon state of Para is part of the so-called "arc of destruction,'' the southern edge of the rain forest that has been devastated by loggers. In 2005, American missionary Dorothy Stang was shot dead in the region during a land dispute.

On Tuesday, the Greenpeace activists tried to haul away a badly burned fallen tree trunk for an exhibit on global warming in Rio de Janeiro and Sao Paulo, Muggiati said.

He said the federal environmental agency Ibama gave Greenpeace the OK to transport the tree trunk, but the permission was suspended in the wake of the standoff.

Thankfully, our team managed to get out of there in one piece. This isn't the first time we've had to deal with this kind of intimidation in Brazil, but our work there is making a real difference.
