Israel has carried out a strike inside Iran, a US official told CNN Friday, a move that threatens to push the region deeper into conflict. The target is not nuclear, the official added.
Iran’s air defense systems were activated in several locations after three explosions were heard close to the airport and an army base in the Iranian city of Isfahan, state media reported early Friday morning.
Three explosions were heard near a military base where fighter jets are located in the northwest part of Isfahan, Iran’s semi-official FARS news agency reported.
“The defense is activated in response to an object that is likely to be a drone,” sources told FARS news. The news agency reported that a possible target of the blast was a military radar, and that the explosion broke several windows of office buildings in the area.
Tensions remain acute across the Middle East after a decades-long shadow conflict between Israel and Iran erupted into the open this month raising the prospect of an all out war.
Reports of the explosion come hours after Iran’s Foreign Minister Hossein Amir-Abdollahian told CNN that if Israel takes any further military action against Iran, its response would be “immediate and at a maximum level.”
