Iranian state media report explosions on Qeshm Island in the Strait of Hormuz and in the cities of Jask, Sirik and Bandar Abbas, according to Al Jazeera's live blog for 8 November.
The cause of the blasts has not been established. The reports do not attribute them to the US, and they have not been independently checked.
The reports come after Trump confirmed "minor strikes" on Qeshm on 6 November.
