ZIMBABWE: The spokesman for Zimbabwe's main opposition leader was beaten by security forces as he tried to leave the country.

Nelson Chamisa, aide to Movement for Democratic Change leader Morgan Tsvangirai, is "critical" after being hit with iron bars at Harare Airport as he prepared to leave for a meeting in Belgium. He is now in hospital in Harare.

The assault follows the re-arrests at the airport on Saturday of three opposition activists, who were allegedly assaulted along with Tsvangirai when police broke up a March 11 protest meeting.
