zimbabwe: Tsvangirai must answer treason charges-prosecutors

State prosecutors argued on Wednesday against calls for the treason case against Zimbabwe opposition leader Morgan Tsvangirai to be dropped, saying he must answer charges he plotted to kill President Robert Mugabe. Tsvangirai and two senior colleagues in the Movement for Democratic Change (MDC) could face death sentences if convicted of plotting to assassinate Mugabe in 2001 amid Zimbabwe's worst political and economic crisis in decades.
