“As part of the ongoing attacks carried out by the Zionist and American enemy, the gas administration building and the gas pressure regulation station on Kaveh Street in Isfahan were targeted,” said the Fars news agency.

The facilities in central Iran were “partially damaged”, added Fars, which was Iran’s only news outlet to report the incident.

It said an attack also targeted the gas pipeline of the Khorramshahr power plant, in the country’s southwest.

“A projectile hit the area outside the Khorramshahr gas pipeline processing station,” Fars reported, quoting the governor of the city bordering Iraq.

It did not specify the extent of the damage.

Trump told AFP on Monday that “things are going very well” with Iran, shortly after announcing talks with Tehran and a five-day pause on targeting the Islamic republic’s power plants.

Trump’s abrupt shift on Iran came hours before the expiration of a two-day ultimatum under which he threatened to attack Iranian power plants if Tehran did not reopen the strategic Strait of Hormuz.

Iranian media however said on Monday that there were no negotiations underway towards ending the war.
