Explosions echo from Tehran to Shiraz, Iranian army on alert

Suspicious explosions were heard in the Parand area of ​​Tehran as well as in the mountainous areas of Shiraz province. The real reason behind these blasts is not yet clear. While on one hand the local media is calling it an accident, on the other hand defense experts believe that it could be part of a major cyber attack or intelligence operation. The Iranian fire brigade has claimed that the fire has been brought under control, but there has been no official confirmation of any casualties. Iran has completely rejected the news of any external attack.

Satellite images reveal the secret: ‘Concrete siege’ of nuclear centers

Amidst this tension, the most shocking revelation has come from satellite images. According to the report, Iran has destroyed its most sensitive military bases. Parchin Military Complex (Parchin Military Complex) has intensified its fortification. The photographs show that the buildings damaged by the Israeli attack in October 2024 have not only been rebuilt, but a thick concrete shield has been built over them and covered with soil. This technology is being adopted to protect important assets from air attacks and missile attacks.

Entry gates of tunnels sealed in Isfahan and Natanz

Not just Parchin, but Iran’s main center of uranium enrichment Isfahan Nuclear Complex War-like preparations are visible here too. Satellite images showed heavy machinery and trucks sealing the entrances to the tunnels with mud and concrete. Taking lessons from the damage caused by American attacks last year, Iran is now trying to secure its nuclear program. There are indications that the work of repair and strengthening of protective structures at Natanz sites will be completed by February 2026.

Talks fail and crisis over Oman’s mediation

Recently, indirect talks were held between Iran and America in Geneva with the mediation of Oman, which remained inconclusive. Although Iran’s Foreign Minister called it positive, America has bluntly said that Tehran is crossing their ‘Red Lines’. Amidst this diplomatic deadlock, Iran has sent a message to the world by testing missiles in the ‘Strait of Hormuz’ that it has the power to stop the global oil supply. Experts believe that Iran has sensed the sound of war and is building impenetrable fortifications of its military and nuclear facilities.
