A UN official says post-election unrest in Zimbabwe is nearing crisis levels, holding both the ruling and opposition parties responsible. The United Nations resident representative in Zimbabwe, Agustino Zacarias, said on Tuesday that the violence was escalating towards crisis levels with supporters of the main opposition, Movement for Democratic Change, targeted in most of the attacks. He added, however, that MDC were not totally blameless. "There is an emerging pattern of political violence inflicted mainly but not exclusively on rural supporters of the MDC," Zacarias said.
