Tanzania police arrest opposition party official after deadly election protests

Chadema party says deputy secretary general arrested and calls election of incumbent president fraudulent

Tanzanian authorities have detained a senior official from the main opposition party, Chadema, amid a spate of arrests in connection to deadly protests during elections last week.

More than 1,000 people were killed by security forces during the demonstrations, according to Chadema and human rights bodies. The Tanzanian government has said these figures were exaggerated but did not give its own figures.
