A Vietnamese BBC journalist has been blocked by authorities from leaving the country for "several months", the broadcaster said, heightening concerns about press freedoms in the nation.

Vietnam -- a one-party state -- has no free media and clamps down hard on dissent, ranking among the world's leading jailers of journalists with 28 currently behind bars, Reporters Without Borders says.
