Harare: Zimbabwe announced a delay in the partial recount of its disputed March 29 election on Sunday, extending a political deadlock in which the opposition says 10 of its members have been killed and hundreds arrested.

The delay increased opposition concern about possible vote-rigging by veteran President Robert Mugabe's Zanu-PF party. The recount could overturn the results of the parliamentary election, which showed Zanu-PF losing its majority to the Movement for Democratic Change (MDC) for the first time.

Results of the parallel presidential election have not been released, but MDC leader Morgan Tsvangirai says he has won.

"I can confirm that 10 of our members have died, four of them in the last few days, due to political violence perpetrated by ruling party supporters in the aftermath of the elections," MDC spokesman Nelson Chamisa said.

Instability

Amid mounting regional concern about instability and bloodshed, the 53-member African Union urged Zimbabwe to release the election results immediately, and called for restraint from all parties.

African leaders have come under international pressure to take strong action to help resolve the crisis in Zimbabwe, a once prosperous country whose economy is in ruins, beset with rampant inflation and mass unemployment.
