WINDHOEK, Namibia (AP) — Namibia has sent more than 500 soldiers to help battle a huge wildfire that has burned across 30% of the country’s best-known national park. The park is home to hundreds of species of wildlife, including critically endangered black rhinos. The president’s office said the fire had also spread into villages on the outskirts of the park, but no human casualties have been reported. The Etosha National Park is one of Africa’s largest and is renowned for its salt pan that turns into a lake during the rainy season and attracts wildlife. Namibia is a hot, arid country in southern Africa and the fire came in the midst of the driest time of the year in Etosha.
