Iranian media say no strikes have been reported in Hormozgan province, despite the sound of explosions near Jask, according to Iran International on Friday.
The Iranian media reports suggested the noise may have come from the armed forces confronting vessels that they say violated maritime regulations. The cause has not been independently verified.
This sits uneasily with Thursday's statement from the state news agency IRNA. Citing official sources, IRNA said Sirik, also in Hormozgan near the Strait of Hormuz, had been hit by an 'enemy' attack of a military nature. It gave no details of damage, casualties or who was responsible.
Fars News Agency, which is affiliated with the IRGC, had earlier said some sources linked the Sirik explosions to warning shots toward 'violating ships'.
There has still been no claim of responsibility from the US, CENTCOM or Israel.
