Afar and Saho: Hirg-Higo, alternately Archigo, Arqiqo, Ercoco, Hirgigo, Hargigo or Harkiko) historically known as Dokono is a town in the Northern Red Sea region of Eritrea.

This town was the site of a terrible massacre by the Dergue military junta of Ethiopia in 1975, during the Eritrean War of Independence.

The region is reputedly one of the hottest inhabited places on earth, with temperatures soaring well above 40°C (104°F) for much of the year, combined with an average annual rainfall of less than two centimetres (an inch).

Formerly covering significant portions of the Eritrean coast, original mangrove forest was destroyed by overgrazing by camels or cutting for firewood or the building of homes and boats.

It is supported by the Eritrean Ministry of Fisheries, in the hope to restore mangrove coastline boosting the numbers of livestock, fish and seafood.
