Ethiopian soldiers captured by the Tigray Defence Force walk towards Mekele Rehabilitation Centre, in the capital of Ethiopia's Tigray region. According to the Tigray Defence Forces (TDF), more than 7,000 captive Ethiopian soldiers have walked from Abdi Eshir, about 75 km southwest of Mekele, for four days. The rebels marched into the city this week after local officials and federal government troops pulled out, and the government of Prime Minister Abiy Ahmed has since declared a unilateral ceasefire.
