Vietnam charges US citizens with terrorism
No - all they did was broadcast anti-communist radio transmissions. BBC, US citizens on trial in Vietnam:
Three US citizens and four Vietnamese have gone on trial in Vietnam charged with terrorism.
The seven are accused of attempting to set up illegal transmitters to make anti-communist radio broadcasts inside the country.
The case may complicate ties with the US ahead of President George W Bush's visit to Vietnam next week and a Congressional vote on trade relations.
The trial in Ho Chi Minh City is expected to last no more than a day.
