Harare - The European Union is "deeply concerned" over the welfare of Zimbabwean activist Itai Dzamara, who was abducted exactly a month ago and is still missing, the EU delegation to Zimbabwe said on Thursday.Father-of-two Dzamara was taken away half-shaved from a barber's shop in Harare by five men driving an unmarked vehicle on March 9. The former journalist had been calling on President Robert Mugabe, 91, to step down.Although lawyers obtained a court order forcing police and authorities to search for the activist, no progress has been made. The opposition Movement for Democratic Change says that it holds Mugabe and his government directly responsible for Dzamara's disappearance."The EU reiterates its call on the government of Zimbabwe to take all necessary measures to ascertain Mr Dzamara's whereabouts, safeguard his well-being and accord him the full protection of the law," the EU statement read. "'The EU delegation remains deeply concerned for his welfare."Dzamara's wife wants the head of the Zimbabwean police force, the head of the secret service and Zimbabwe's home affairs minister, Kembo Mohadi, to be found guilty of contempt of court, rights lawyers said earlier this week.Aid groups are reported to be mulling offering a reward for anyone with information on Dzamara's whereabouts.Former vice president Joice Mujuru also highlighted Dzamara's disappearance in a rare public statement published on Thursday that was highly critical of her former colleagues in Zanu-PF."One wonders if the [politburo] ever spared any moment to enquire on the disappearance or lack of news on the whereabouts of Itai Dzamara and what his young family is going through," she said.
