unrest

The resulting unrest and violence have sent refugees fleeing westwards into Mauritania.

Zuma-Sambudla, 43, has been accused of fuelling this unrest and faces charges of incitement to commit terrorism and public violence.

Opposition parties estimate that as many as 1,000 people may have been killed in the unrest.

Hundreds may have died in post-election unrest according to the opposition.

Earlier a Tanzanian police spokesman said the country had intelligence that some foreigners had crossed the border through illegal points "with the intention to commit crimes, including causing unrest".
