Tanzanians planning to protest on Tuesday against government repression are facing a heavy police presence and warnings from authorities, which recalls the mass killings that followed last October's disputed election.
Riot police with weapons drawn have been visible across Dar es Salaam, Tanzania's commercial capital, following calls for protests on 7 July, a date usually marking a celebration of the Tanganyika African National Union, the party that led Tanzania to independence in 1964.
