Where was the World Summit on Sustainable Development (Rio + 10) held?

The World Summit on Sustainable Development (Rio+10), commonly called the Johannesburg Summit, took place in Johannesburg, South Africa, from 26 August to 4 September 2002. The United Nations’ official page for the 2002 conference describes the event as the World Summit on Sustainable Development held in Johannesburg and notes its Political Declaration and Plan of Implementation adopted there [1]. A WHO report summarising outcomes likewise states the Summit was held in Johannesburg, South Africa, in late August–early September 2002 and links it explicitly to the ten-year follow-up to the 1992 Rio Earth Summit [2]. These authoritative sources confirm Johannesburg as the correct location for Rio+10.
