One person was killed and several others were wounded in a bomb attack near a mosque on Tanzania's Indian Ocean island of Zanzibar on Friday, police said.
The east African nation of Tanzania marks its 50th birthday this weekend, but celebrations are being overshadowed by a tussle over the union between the mainland and the islands of Zanzibar.
The death toll from a building which collapsed in Tanzania's economic capital Dar es Salaam reached 25 Sunday, officials said as hope faded of finding those missing two days after the accident.
