At least one person was killed and 10 others injured in skirmishes at an opposition party rally in Kwekwe, central Zimbabwe, on Sunday. The BBC reports that The Citizens Coalition for Change supporters were attacked by a group of men armed with spears, machetes, iron bars and stones. The violence forced party leader Nelson Chamisa to abandon his address. The CCC blamed President Emmerson Mnangagwa’s supporters for the violence, a charge the ruling party rejected. It comes as rights groups warn of increasing violence ahead of crucial by-elections scheduled for 26 March.
