The United Nations has called on Tanzanian security forces to refrain from using unnecessary or disproportionate force against those protesting the country's disputed election result. The UN says every effort must be taken to de-escalate tensions and has appealed to protesters to demonstrate peacefully as the main opposition party, CHADEMA continues to call for protesters to take to the streets of the commercial capital Dar es Salaam and other key regions. The government has also faced criticism from rights groups who have accused it of blocking connection networks, including internet access, amid fears that hundreds have died in days of clashes. This comes as President Samia Suluhu Hassan has been declared the winner of the country's disputed poll with nearly 98 percent of the vote, after leading rivals were excluded from the race. For a look at the situation on the ground, Elvis Presslin spoke to Hussein Khalid, the CEO of Non-Governmental Organisation Vocal Africa, based in Kenya.
