Hundreds of people have died in three days of post-election violence in Tanzania.

The British media outlet BBC, citing diplomatic sources, said at least 500 people had been killed. A spokesman for Tanzania's opposition Chadema party told AFP that nearly 700 had been killed.

Violence has erupted since the election was held last Wednesday. A large number of protesters have died in clashes with security forces. The government has issued a curfew order following the unrest. 

A large number of young people are participating in the protests. They started the demonstration saying that the election was not fair. One of the opposition leaders is in prison, while the leader of another party was barred from participating in the election citing technical reasons. 

Therefore, President Samia Suluhu Sahan's Chama Cha Mapinduzi (CCM) party is expected to be ahead in the vote results.
