Two 18-year-old British girls who had been volunteering at a school in Zanzibar where injured when assailants threw acid on them. No arrests have been made, but Islamist militants are suspected. The Uamsho, a group that wants to impose sharia law in Zanzibar, has clashed with police in the past. Two Christian pastors were killed earlier this year in separate attacks but no suspects were named. The Committee to Protect Journalists noted at least 10 attacks against media personnel in Tanzania in the past year. A Christian news outlet reported earlier this summer that attacks on Christians have increased, and that pastors have received death threats and churches have been torched.
