Following visits to three maximum prisons, the first in Tanzania by a head of state, President Jakaya Kikwete has pledged to ensure that prison conditions improve and prisoners are treated humanely. "The aim of my visit was to learn about what is going on and I promise that the government can look for solutions, particularly on the issue of overcrowding in prison," Kikwete said. For years, human rights activists have complained against appalling conditions in Tanzanian prisons.
