Zimbabwean Pastor Evan Mawarire addresses students during a lecture at Wits University in Johannesburg, on July 28, 2016. Mawarire, who said he has no political ambitions, became the public face of a wave of protests in Zimbabwe as founder of the popular "This Flag" internet campaign and an organiser of a national strike. The country's long-standing economic troubles have deepened in recent months, with Mugabe -- aged 92 and increasingly frail -- now struggling to pay soldiers and civil servants. / AFP / MUJAHID SAFODIEN (Photo credit should read MUJAHID SAFODIEN/AFP/Getty Images)
