HARARE: Zimbabwean police on Tuesday arrested two more senior members of the country’s war veterans’ association in a growing crackdown on critics of President Robert Mugabe, lawyers said. Headman Moyo, the Zimbabwe National Liberation War Veterans Association (ZNLWVA) vice chairperson and his Harare provincial counterpart Hoyini Samel Bhila were arrested on charges of undermining Mugabe’s authority, bringing to five the number of former liberation war fighters arrested under the same law. “Police charged Headman Moyo and Hoyini Samuel Bhila after the two handed themselves to detectives at Harare central police station,” Zimbabwe Lawyers for Human Rights said in a statement. Mugabe, 92, in power since 1980, has faced a groundswell of opposition in recent months as the country’s moribund economy collapses and the government struggles to pay its workforce. Previously loyal supporters of the president, the war veterans released a highly critical statement two weeks ago attacking Mugabe as “dictatorial” and accusing him of being unable to address Zimbabwe’s problems. Mugabe has promised “severe” treatment of the statement’s authors.
