More than fifty black youths were arrested today in Harare, Zimbabwe, when police broke up demonstrations at South African offices and the US embassy. Julie Fredricks reports. A group of more than a thousand students and youths caused thousands of dollars of damage by burning and stoning the offices of the South African trade mission, South African Airways, Air Malawi, and the Malawian High Commission. The demonstrators suspected South African complicity in the plane crash that killed Mozambiquan President, Maehel in South Africa and blamed Malawi for supporting the Pretoria-backed insurgents that are attacking Mozambique. Zimbabwean government officials appealed for calm, and a statement from Prime Minister Mugabe just back from a trip to London is expected tomorrow.
