A variant of napalm was produced in Rhodesia for a type of ordnance known as "Frantan" between 1968 and 1978 and was deployed extensively by the Rhodesian Air Force during the bush war. In May 1978, Herbert Ushewokunze, minister of health for the Zimbabwe African National Union (ZANU) produced photographic evidence of purported civilian victims of Rhodesian napalm strikes, which he circulated during a tour of the US. The government of Mozambique and the Zimbabwe African People's Union (ZAPU) also issued claims at around the same time that napalm strikes against guerrilla targets had become a common feature in Rhodesian military operations both at home and abroad.
